Is there a true bolt on rear disk brake kit? I have spent hours searching and reading and it seems you always have to fab lines or brackets or grind parts etc? Does anyone make one that really just bolts on?

I doubt it since not all cars were built exactly the same back in the day. Today I would say because so many robots are used in the assembly process of building a car that all cars built are pretty much the same as the car built next to it. So my answer would be there close but you still will have to do a little fab work or adjustments to make it fit.

Our kit is about as close as it gets. We provide direct replacement Ebrake cables that clip to the original intermediate with stock clips.

Our bracket bolts the the stock flange, rotors slide over stock axles (rarely you need to turn axles) and the caliper slides on. We provide rubber flex hoses and CAN provide rear axle hardlines already shortened.

Let me know if you have more questions or need more details!
