[Healeys] BN2 Trans mounting

[Bob Spidell]

I got dowel bolts from BCS (they weren't cheap). Some say you don't need 
them, but I work on the 'If the beancounters at BMC allowed them ..." 
principle. I helped a friend convert his early Camaro to manual; the 
instructions from the transmission company were quite specific about 
alignment of the bell housing to the engine.
