Default Re: How are 28-29 and 30-31 radiators different?

Thanks, GRutter, BobC, and of course, Steve Plucker for giving me info and your perspectives!
BobC, I measured the distance from the front of the fan blades to the back of the radiator core (fins), and it's about 1 3/4" as best I can tell, and that looks to be too much, and way more than it was with the old cross member. It looks as if the return neck (top) on the radiator and the neck on the engine would line up fairly well if they were closer, but my old upper hose is a little more than an inch too short. Steve, thanks for your offer for names of local members--I'm afraid I've got such a hybrid situation (maybe a transitional radiator, definitely not the same return neck as a 28-29, etc.) that I couldn't tell much while in the car other than they're all different.
I spent some time going through Brassworks' website today, and I thought I might call those guys on Monday and see if they could give me some dimensions and specs so that I could compare apples to apples.
