The guys are right. The Richmond 5 speed is a bullet proof tranny with 1 to 1 5th gear ratio just like the 4 speed and should be a relative easy install. Things like rear tranny support, drive shaft length etc. will have to be addressed but that isn't a big problem either. There is more than enough members here to help with you with issues when you are ready to do your swap.

Hey Dep
Me too...but unfortunatly it's not a plug and play conversion to the clutch safety switch. I tried...didn't work. The wires must be run from the auto switch near the shifter, to the clutch switch under the dash....or completely tear apart the dash harness. I'd just run the wires!!
Been soooo busy lately Dep (son graduating H.S.) haven't had time for anything. I WILL however get up to see ya soon.

Eddie: I think the clutch neutral safety switch would work if you also replaced the wiring from the firewall to the starter with a stick shift car. Since I need to replace BOTH those harnesses anyway, I will use the stick shift versions. Anyway, I can always solder those two auto purple ones if it doesn't work

Dep
P.S. Understand about being busy. Whenever you get the chance is fine

Thanks again for all the help, personally i think i would want the four speed, and doing it under 2g's sounds very comforting. I'm wondering what the difference in fuel economy will be between the 4-speed as opposed to a 5 or 6 speed.

Also, i'm glad you guys mentioned the electrical part, i'm sure i would have overlooked that.

Is there anyway to save these threads so i can view them down the road when i actually attempt this?

thanks again

jc: What I do is copy and paste into Windows notepad. I got a desktop full of hints and methods
You can also copy down the web address and paste it in your browser
to access it again. But it's not as reliable as pasting the whole text into a notepad entry.

If you are concerned about fuel economy you need to think about a few things. How are you going to drive the car? You gonna drag it, race it on the track, cruise in it? What ratio rear end do you have? With a four speed and a 3:55 to one ratio rear end you will be running about 3,200 rpms at 70 miles per hour. For a drag car its not enough and for a cruiser its too much. If you are going to road race your car a close ratio 4, 5, or even a 6 speed is the answer. Shifting gears is great, drag racing is great, but you need to decide how you want to drive it to set it up best for you. Going from a 4 speed to an overdrive 5 speed could mean going from 16 miles per gallon to over 20 depending on your rear diff ratio. We all want you to make the decision that is best for you. Even an automatic overdrive is an alternative if you just want to drive the car and get decent gas mileage. They don't do bad either as drag cars. We have guys that love to build them any way you can imagine to drive them. Quarter mile runs, twisty tracks or open road cruising; they are here to help you with whatever you decide. We each love what we enjoy and it seems that we try to push that on people but we really want you to enjoy driving it the way you want to. Think about it, tell everyone how your car is set up now and what you want it to do. If you can dream it these guys can tell you how to make it happen!

It's not just the fuel economy when looking at a 5 or 6 speed. It's:
Higher top speed
less wear on the engine
less wear on your ear drums
strong, modern tranny
making your car suitable for long interstate trips
etc...

I converted my Silver '75 coupe over the winter for about $1700. Also at that time put in a new GM 260hp crate motor.

Hi Robert,
Like I said...no offense intended. It's just not for all of us. I
don't drive on the street and I have no worry about fuel economy, engine wear, or engine noise. All my trips are only 1/4 mile long. If I ever move up to something with 5 speeds (which would probably be when I won the lottery), it would be a Lenco or Liberty or Jerico or possibly Richmond.
I know you guys make a great product and fill a need for those who drive on the street.
