[Healeys] BN2 Trans mounting

[Curtis Arndt]

Michael,

The top right and the bottom left bolts are special BSF "Dowel Bolts" while
the rest are 3/8" Whitworth [BSF] hex bolts of varying lengths.

I just happen to have a completely restored BN2 bell housing for sale
currently on eBay...

You should get a lot of information from my pictures, then ask questions.
