Merry Christmas and Happy New Year to you and yours Tony! The 68 radiator support was simply a 67 support made to fit the new 68 inner fenders. They really did not have enough air flow and that is why, along with the million other things on 68's, they were changed in 1969. Scott is right, the 69 supports mount to the lower front crossmember. Your friend Lou.

The pace is picking up...I finally unlocked my brain to get the fender placed on the frame....by rebuilding the DIY radiator support and tilting the radiator 35* to make room for the future condenser. It's a mess but it will work...I think...
The primer bled thru the Satin Black...ohh well...2 more coats will hide it....
Y U G L Y..... sandingm required.....the big block radiator needed some extra angle and needed sliding rearward a couple inches for the condenser to fit.....
The extra inch I added to the rear of the passenger fender gets the 1st rough trim to get the contour correct..........
The wheel is now centered in the wheel well (after 10 months)........
Once I sand the fender to door gap 3/16" wide and add body filler to the repaired fender arch this side will be done and gets prepped for painting.
The driver side fender needs lots of repairs but should go together easier now that I have a clue and can copy off the passenger fender.
THAT will teach me to remove a front clip that is aligned alresdy
UPDATE: I changed the DIY radiator support AGAIN so I can remove the Rad. from the front of the support without removing anything else. I still need to weld the driver's side half of thr DIY support in place now that the radiator is titled rearward enough for the hood to close (which it would not do today when I test-fitted the hood).

Just clowning around after errands......
That weird looking experimental fan shroud worked well by drawing in ambient air from ducting (not installed yet), so I will DIY a custom shroud before dropping the radiator into the support....
The 2000 CFM Puller fan is installed on the reat side of the radiator. I will install a 2000 CFM pusher fan on the front of the condenser....
My friend Gary made me a piece of wall art......
Maybe I can wrap up the radiator work tomorrow

I bent up a fan shroud housing out of aluminum and put a similar fan in it, it works great but be sure to seal it so it gets a great draw across the rad if you go this direction. Looking good Doorgunner, and a Happy New Year Sir ... in keeping with the situation.
Do you think you’ll really need two fans?
Just thinking out loud!
Yep Two fans put 50% more air thru the condenser/radiator setup.

Whats that joke ? Harley riders gripe about the fan noise!
You guys told me to put a 10 second delay relay on the puller fan,,,works great...no alternator spike.

It works well, but your method should really help. Annnd...I have the room to add the electric fan shroud like the Big Boys use! Back Atcha"

The A.C. condenser is fitted for an air gap between it ans the radiator core. I will have to remove the OEM supports from the condenser and fab 4 supports......
Tomorrow I will fab a new hot radiator air deflector shroud to send the radiator air directly under the engine crossmember.
I need to order some synthetic flexible duct tubing to draw ambient air from the headlite area.
Right now the hood has about 3/4" gap from the radiator upper support

Good job...I wish the GM engineers had the radiator tilted forward and vented the hot air through the top of the hood loke the Ford Cobra GT Daytona cars...would have been a lot better cooling.
Tony do you have a stock clutch fan behind the wash tub to draw in cold air for the motor?

Totally agree. Not only that, but looks cool as can be too.

Yessir...I found one in a box which puts the fan about 3" deep into the round shroud/5" of "Vacuum chamber where the 3" adjustable ducts are riveted onto the shroud....I also trash-canned the experimental flex fan that sat too close to the shroud opening at the water pump.

ME TOO! bUT TOMORROW i HAVE TO FAB THE HOT AIR DEFLECTOR SHIELD THAT FITS BEHIND THE RADIATOR.

On my '34 street truck it was running about 200*F with a 180* thermostat so I added another radiator under the bed with a pusher fan and high volume water pump to cool things down (now I realize I could have added a puller fan to the front radiator along with the pusher fan rather than spending a day adding the 2nd radiator
ANYONE WANT TO TAKE A GUESS WHERE I BOUGHT THE NICE ROUND FAN SHROUD???
