I got motivated this week and removed the rest of my AC stuff. Now I have this ugly hole on my firewall, but wonderful new room on the right side of the engine. I'm putting the fan motor back in because I need heat and defroster. Anyone other than acdelete.com that makes plates to cover this mess up. They don't seem to have one for the Corvette. Anyone make a custom cover that keeps the heater/defroster and fan motor functional?
I think I loss less than 10lbs doing this, but it really opened up the passenger side engine bay.

I'm looking to do the same thing

 

Are you doing away with the A/C? If so, how come?
BTW: Panic, I believe, made a cover out of aluminum. Maybe he has a template of how he made it.

 

I took the compressor out over ten years ago when Freon went out the roof. I never got around to removing all of the other stuff. I think Panic did away with his heater also, I'm trying to keep the heater functional.

i removed both and then made a cover outta plexiglass n painted it black and hung my coil n my MSD ignition off it. was a bit worried about it melting but after 14yrs on there i don't worry anymore

 

I'm hoping to do this in the near future, I've been watching acdelete.com as they say the Corvette unit is coming soon. Was this hard to do? Did you split the unit in half to remove?

 

Just a thought but you might want to call Hot Rod Air or Vintage, etc to see if they'll just sell you that one part.

 

i did this so long ago i don't remember, all i remember is installing a new heater core n driving down to ecklers reunion show in florida n the damn new heater core leaked all over the passenger footwell so i just bypassed the tubes n just yanked everything outta there including the heater controls n ducts, no more heat or air but sure coulda used the heat a few times but don't miss the air.

 

It's a real pita. Lots of hidden screws and nuts. The unit is designed to come out in halves, but after trying to pry it out a few times with screws or nuts not seen still in place will help break it up in fourths. I guess if I'm going to keep heat, I'm going to need one of those acdelete pieces. The air flow has to move from the fan to the heater element thru one. I guess I could leave the blower fan out of it, but the heat would just have to rise up to the windsheild to defrost it. I'll call acdelete tomorow.

aah? put a non a/c heater box in its place

vc

 

That's what I did with my '76. Makes for a smaller, less complicated box inside and out. Takes a little time to gather the parts up, but it worked out well.

I took away both A/C and heater (with all ancillaries), for the firewall hole i made a simple alu sheet and screw it there, it looks cleaner and gives a new 'fresher' look to the whole engine bay.

 

I bought one of these;

It is a fiberglass cover looks good. I had to drill the holes and make sure your heater controls are set in the off position when/if you istall it.

 

I called AC delete today. Their voice mail is full. I sent an email. Hopefully they will get back to me.

Why not just paint BUBBA WAS HERE on your car? Why would you remove AC on your C3? Like it or not, it brings big $$$$$'s (if it works)

 

Don't think BeeJay is planning on selling anytime soon.

 

...seems as though I've seen hundreds of C3s over the years for sale where "A/C needs charged" is more common than "numbers matching" I've also personally known many, many C3 owners who have put hundreds $$$(a few a thousand $$$)into their A/C systems only to get their car out next season and the A/C refrigerant completely gone again. My '75, being my "daily driver C3" when the weather is decent with 163,000mi and a 17yr old Maaco paint job is not worth the money and effort(to me anyways)to replace, repair and keep charged the A/C system on a 33yr old car. to those that do, but I don't.

...when I changed my car over to a 4spd and put in a 260hp 350ci crate motor 4yrs ago, I removed my A/C and darn near made it look so factory, a pretty good C3 person would really have to look close to see that it was an original A/C car. A few "small" giveaways to those that know, my car still has the "blocked rear window deck vents", the small A/C vent to the lower right of the steering wheel and "missing" levers on the main console for the side cowl fresh air inlet doors. I did learn a great deal about the difference between an original A/C car vs an original A/C car. There is more to the original A/C car than one might think. For one, there is a vacuum operated pod that opens and closes a fresh air door on the passenger side wiper cowl area and a lower one next to the passenger side footwell cowl. These two "fresh air doors" open and close depending on the demand of the A/C controller. I even bought the "non A/C wiper switch bezel" above the center gauges and removed that middle A/C vent bezel. I had to change out the "inner passenger side heater box" and remove the larger A/C heater box. I believe '69-'79 were the same. '68 was a simpler, cable operated vent/defrost door set-up, not vacuum. I further purchased a "non A/C rebuilt heater controller", the non A/C engine side heater core cover and a non A/C heater core. Once the "large" A/C ENGINE SIDE housing is removed, you can get a non A/C engine side housing and fit it over the large hole. From this point, make a sturdy thin cardboard template covering the exposed opening and overlapping it an inch or so. Then make the same design out of heavy sheetmetal noting exactly where to install it. The after installing it and fastening it, you can feather the edge with like a plumber's putty or like material. I kinda wish now I'd kept that template design I made as it came out GREAT. I even purchased the "non-A/C" heatcontroller wiring harness that takes the place of all the A/C wiring harness. The non-A/C wiring harness goes to the non A/C controller, to the resistor set-up that drops the voltage to the fan motor for your fan speeds, then along to the fan motor. I did it "so correct" other than the little differences I mentioned earlier, it looks FACTORY. I've heard alot of good compliments at shows where I've heard people say, "Cool, look a non A/C 4spd '75 coupe, Silver on Silver Leather"

...I for a moment DO NOT regret what I did and I got a fair amount of $$$ for the all the complete A/C stuff. Paid for more than half of the parts I needed to make it a non-A/C car. And I have a GREAT, stock working heater-I still drive it in the winter, but on nice dry, clear roads.

 

I paid big bucks for the optional AC in 79. I was stationed in Florida and then Houston. But I've been in Cali. since 88. I leave the top off most of the time and freon has gone unobtainable. I'm never selling this car, so to heck with the resale value.

I'm sorry it took so long to get back to everyone on this, but I finally got my AC delete plate in.

The picture of it installed doesn't look so hot. I'll have to take it in the daytime.
But it's a good product. You have to drill all of your own holes, but they dimple it where you should drill, making it Bubba proof.

 

...kinda funny all these people wanting A/C cars in the hobby, then you have people like me and also several posters here yanking it out. In my case, my A/C system was totally shot, evaporator, condensor, missing A/C compressor, blown main high pressure compressor hose, etc. Since I don't like A/C, and the last three new vehicles that I purchased were A/C "delete" ones prove it, I had to remove it from my '75. I don't regret it one bit either. Yeah, I may have "de-valued" my car somewhat, but how much can a '75 coupe with 174,000mi driven 6,000mi per year and a $485 Maaco paint job be worth anyways???
