Finally finished my billing for the last period and cross-referencing the brake calipers for a '67 Iso Rivolta. The fronts are Girling units originally spec'd for various and sundry Lamborghinis, and the rears are Girlings designed for several Aston Martin applications. Iso picked existing parts off the shelf to design their cars around. Smart. Now to see if our parts guy can source them.
Iso Rivolta
Normally I'd rebuild the damm things myself, but the owner of the car had some bozo work on it, and he sent all the calipers off. They got scrambled. So NOW, the calipers we have with the car, though they're all brandy-new rebuilt by White Post, don't actually go to an Iso of any description. Totally USELESS, and the rears won't even physically bolt to the DeDion rear-end center section.
Least I can hand off finding all the stuff now, 'cause I have the CORRECT part numbers I need to fit this particular car.
For the record, the front calipers that came in with the car fit a DeTomaso Mangusta, and the rears fit a Daimler SP 250.
Maybe I can finally get some model-car bench time in today.
