Thanks guys - helpfu

External route maybe best but I may not have the room. Been in touch with the Keisler guys and they have been helpful and thgink they have the right kits and that it will be strong enough etc. I have a small issue in that the car is in UK and I cannot check the specs it came with, but am assuming a TKO 600 mated to 460 BB through Mcleod clutch is a known set re bore/shaft sizes etc. The guys at Keisler seemed to act as if he knew by definition it would be right.

Cheers
