Hello Everyone, I need to pick someone’s brain about a conversion issue. I recently bought a 1979 Brat and am attempting a rear disc conversion. I pulled the backing plates and calipers from a 1986 GL-10 Turbo. The backing plate bolted onto the rear trailing arm after removing a quarter inch off of the back of the arm. Then I ordered some new rotors (made for an 86 GL-10), then I pulled the hubs off of a set of gen 1 brat front brakes I had lying around and my intent was to bolt the hub directly to the new rotor. However, as I was getting ready to bolt the hub and rotor I found the bolt pattern did not exactly line up. I took some measurements and found the gen 1 brat hub has an approximate pattern of 4 x 90 and the new GL-10 rotors have an approximate bolt pattern of 4 x 100. So my question is are the hubs from the mid 80s slightly larger than this of the gen1? Thanks for any help you might give.

I had planned to do this after I resurrect the brat and get it in running condition. Any idea what this might have come out of or what the modes number might be or where it is stamped on the housing? Also will this bolt up to an EJ22 with an adapter?

The side of the transmission is tagged with TF-1. I can’t find any info on this at all.
