318 auto to manual swap pilot bushing wont fit?

Good info, but I would call Wayne at Brewer's.
He will have the info on what to do to install it correctly.

If the factory bushing will not fit, use the later model...........

But, you may need to either drill the crank deeper, or cut the input shaft on the transmission and possibly polish step off on the input shaft by the splines, to fit the later model bushing.
