8.75 disc brake conversion kit without parking brake

But if anyone is interested I found a disc brake kit that doesn't use the GM calipers with a built in parking brake. But if you decide you could switch the calipers out for the Parking brake equiped calipers if so desired at a later date, from what I understand talkin to the guy.
He also builds kits for both the tapered axle shaft and the flanged axle shaft. So if you have a pre-1965 8 3/4 rear and don't want to go thru the hassle of converting it over to the flanged axle shaft then with this kit you don't need to. And it fits in a 14" steel wheel. This is the route I'm going with the DeSoto. I'm keeping the tapered shafts. If you are thinking of doing this you will need to sacrifice the brake backing plate because the seal is built into the backing plate on pre-1965 8 3/4.
