Radiator Support
My buddy had replaced the core support on his 1966 F250 4x4 some years ago and still had the old support. I cut what I needed off of that support and tig welded it onto the one from my 2WD truck.

The main portion of the supports are identical. But, the 1966 2WD support has the extra nuts built-in for the battery tray (which is underneath the floorboards on the 4WD) and the brackets to support the inner fenders where they meet up with the support. A few other holes here and there on one versus the other, but the bulk on all the supports is identical. It would be interesting to compare a 1965 2WD beside the 1966 2WD support. As I understand it there are some differences in the inner fenders so the support brackets for them are slightly different. Not sure what all else.

Mine is actually going to end up being an air ride 4wd. So I'll be making some alterations to the inner fender on the left side anyway.
I think I'll shop for a used one first, and if I can't find an exact match I'll take what I can get and splice it in.

PS. finished taking the cab off today, made a wood 4 wheel dolly to make it mobile, going to pull the '66 LWB 2wd and the '79 shorty 4wd into the bay tomorrow and start comparing and designing the air ride system. I cut 11" out of the '66 250 stepside bed and I may splice the rear piece of the 250 frame onto the front of the 4wd 79 frame. The bed will fit better, and the rear of the '79 shorty frame has some rot issues.
