Just got my new Summit catalog and in the featured products pages, Griffin Radiators has a chevy 24 x 16" radiator with 2 1/4" cores for $195.95 (GRI-1-25201-X). This should be a relatively easy swap into an upgraded Fiero. It will most likely require some fabrication, but it will be a whole lot easier than the 26 x 19 install I did for my SBC car (but all the pic links were broken when I switched image hosters....).

Probably drop in. Fiero radiator's 24.5 x 16.5 overall... I'm glad I didn't spend $300 on that ron davis one yet!

It doesn't list the inlet/outlet sizes though

Good choice. I installed a 27.5 X 15.5 (GRI-1-25241-X) griffing rad. I had to cut half an inch from each side of the chasis and modify the upper rad bracket to fit it in and it works perfectly. We get 90+ degrees every day in Puerto Rico and with a 180 tstat and 185 fan switch works like a charm. Good luck with the install. L8tr

It most likely will have 1 3/4 at the top and 1 1/2 at the bottom. My build thread lists the Autozone part #'s that go from 1 3/4 to 1 1/4 and 1 1/2 to 1 1/4 which should make the hoses a non-issue.
