I acquired this rear brake drum to disc conversion kit for my 78 gen 2 10 bolt. I've installed the D52 kit from Wilwood on the fronts. I'm thinking about putting this kit on the rears if it will work. No problems with fit, I did a mock up and everything is pretty self explanatory. Just that I'm trying to figure out what kind of master cylinder I need to go with this. I believe these calipers may be the low drag type that require a step down type master cylinder. I dont know much about this kit. I got it with some rear end stuff I bought from one of the good members I met here. Like I said it does fit. Pretty much I have no money into it so I'm not opposed to doing some thing different. Also might mention I'm converting over to manual brakes. Any advice?
