rear disc brakes

Summit sells a kit pretty cheap.

I wasn't aware that Summit had such a kit. I wonder it it's the same one as the one offered by TSM. TSM uses Eldorado rear disc brakes.


There is also the Scarebird adapters.

Are you using the kit from Summit in the photo with the 8 & 3/4 or is it the Scarebird adapter with parts you need to find?
