Pilot bushing for 4 speed swap

The early SB cranks were ALL drilled for pilot bushings. Some actually got the bushings installed even though it was an automatic application.
You need nothing but a simple, stock pilot bushing to make yours work.
Dont drill anything, dont cut anything..just tap the bushing in.

When you say early SB cranks, what do you mean ?
Year, displacement ?
I'm gonna be dealing with this issue too.

Thanx
