Aaaaaaaand that's about the amount of service I'd expect from T3. If they had even a shitty picture, we'd be able to figure out what it was and whether it would work. Ugh. Never dealt with them, and never will.

If you still want to deal with them, ask them if any of their brake kits will fit an SR-5 diff. They should understand them words. If you want to use a picture it's the diff tube flange to the left in the picture below.


The ST141 caliper mounts are same as drum braked S/T/E series and most likely different to AE86 caliper as the corona stuff has drum handbrake. I could be completely wrong but they are totally different systems.
