Hello Forum Members. I'm looking for a radiator support for a small block aluminum radiator. This would be for a 69 with a 4 speed and without A/C. Part number 3966591.

Thanks

I think I might have one. Will check the part number

I cant find the part number on it anywhere. Do you know where that part # is on the support. This one was pulled from my 69 small block 4 speed. No AC. Here’s some pictures of it:

Pmccooey, your support is a saddle mount for 69 with A/C. or a BB. car.

the mount the poster is looking for is 69 with a 4 speed and without A/C. Part number 3966591.
This support has the sides blocked of for smaller Aluminum radiator, and it mounts on 2 pins mounted on the bottom centered.

That’s weird. My car was a 350/350 4 sod with no A/C. Maybe the support was swapped out at some time?

Thanks 69Vett for clarifying that... you took the words right out of my mouth!

And thanks Pmccooey for the response and posting pics of yours.

I don't see a part number on my current support. I just know that's the part number based on research I've done.

Here are some pictures of the support from my '72 L48 Auto w/AC. It has no rust or rot. There are no welded nuts at the top of the support. It was media blasted and primed at Bonehead Performance and has the first coat of paint on it.

Bob K thanks for posting pics of yours, it looks really nice. Unfortunately the one I need is for a 4 speed without A/C. So the left and right sides of the opening are blocked out making the opening ~22 inches.

The 350 300 HP option without AC or Auto used the 22" stacked Harrison radiator.
The 350 300 HP option with AC and/or Auto used the wider rad.
The 350 350 HP, with or without AC, Auto not available with the 350HP, option used the wider open support yours had. It most likely was original to your car.

Thanks for the information! Good to know!
