Mike Its pretty easy. The master is the same, all you have to do is bolt in the booster and bend the lines a little, and add the vac hose. In fact I just sent you a pm telling you that my master cyl. is bad. I can do most all mech. work so any time you need help let me know. I have most all the tools to do most of the work. Also its very easy to convert to front disc. If you dont mind it being for a 69 and not a 68. 69's use single piston caliper as 68 used 4 piston I just looked at Classic, booster with master cyl is $279.95 I checked Napa and Kragen they dont list any for the Firebird but do for a Camaro, which is the same. Kragen was about $190 for both. These prices were for front disc's though. I think they have the drum brake ones for less $
