Chuck... I bought one with a 7" dual diaphram servo,it gives you a little more clearance although I have heard that some folks have had problems usung a manual trans.
As you can see I had to off-set my X-member (A lack of foresight on my part!) but had no clearance issues with the booster itself.
It's a TH350 trans BTW.
Mine was from Master Power Brakes.
I hope this helps
