just pulled everything from the knuckle out, (spindle, and disc backing plates, and hubs, and always the extra hardware)
got new rotors, calipers and pads.

and you definitely need a DISC master cylinder, from the junker would work if you plan on keeping drums in the rear. if you plan on going disc in the rear, I used a 86 corvette master cylinder, but had to cut about a half inch off the plunger coming out of the booster.

so for 4 wheel drive, the 73 worked great for me.

73 is getting hard to find mid 80's are pretty easy to find

Thanks for all the answers guys but I think I'll go with a new kit after all. The pictures will help when I decide to swap to 5-lug.

Hey 69chevytrucker, you mentioned you used an 85 truck for your parts, did the rear axles come from the same truck? Since our trucks have 12 bolt rear ends I didn't think the mid 80's rear ends were the same, if so that's great. I'm wanting to do this swap sometime as I have all drums also. I've got a lead on a mid 80's truck to use for the brakes, but wasn't sure the axles would interchange.

i lucked out who ever had the 85 before me put a rear out of a 69 im guessing and bought the 5 lug swap axles cause when i pulled the axle shafts out i was shocked they were the right length and they werent supposed to be unless im wrong about the fit but when i took the cover off the rear it was siliconed on
but you could always just use the whole rear end swap it all
