BBP conversion

Did a 186 mile turnaround to Ventura Nationals this weekend while I wait for parts to arrive to do the swap.
I was originally going to call Pirate Jacks about a pwer brake master kit, but I have a stock 63 power brake booster, so all I would need is a 74 master and combination valve.
Has anyone used Pirate Jakc's kit in an early A? There are a couple of connector busses on the firewall right next to the master, and the stock booster utilizes a stand-off bracket to accomodate them. No tsure aout Jack's kit.
