Re: radiator selection
Manual transmission crossmembers are riveted in, automatics are bolted in. Drilling new holes isn't that hard on the bottom of the frame, but the top ones can be tough. A lot of people don't bother bolting it at the top though.
If you have a manual transmission crossmember you will have to remove it.

Re: radiator selection
I pulled and reinstalled two transmissions on these classic trucks. Both were manual. A 1987 chevy 4wd, and a 1981 Ford 2wd. The chevy was missing the extra brace pieces that went to the top flange on the frame rail. I didn't worry about it. The Ford had those braces, but I don't remember if I bothered to reinstall them or not.
Just drill new holes in the bottom frame flange, and call it good. It's not worth the trouble attaching it to the top flange, in my opinion. As far as rivets vs bolts, it'd be REALLY unhandy to do a clutch job without removing the crossmember. Probably impossible on some transmissions. If there's rivets there, cut them off, and replace with bolts.

Re: radiator selection
I should have been more specific, the crossmembers are riveted in on manual transmission equipped Chevy and GMC trucks from 67-72. I suspect they stopped doing that in 1973 when the body style changed.

Been running that setup for almost 4 years now, and it has worked very well. Currently installing a Vintage Air system and finally painting the front clip. |
