Every thing bolts on to original spindles/rear end. The only thing left for you would be the hard lines for the front brakes, assuming you still have the orig type single master. The pre-bent line kit runs around $50-60 depending on who you buy it from, or bend your own. I don't like to ship the lines because they require an oversize box and I'm usually out of stock because they're slow movers due to many buyers decide to bend their own.
The rear kit I sell is exactly like Master Powers 55-64 rear kit. It uses 1969 Cadillac calipers with e brake lever.
Are you ading rear discs for looks or for stopping power?
Front kit $225, rear kit $425, Booster/master/prop valve $175. Guessing at $75 for shipping.
