Bell to block alignment

Any parts house should have straight ones. After you've checked the lateral runout you may find you need the offset ones to get it dialed in. It's a common problem, even with a stock bell housing, and virtually a given with an aftermarket bell.

Couldn't find them in a quick search of their current on line catalog, but Mother Mopar used to sell a set of six offset alignment dowels and listed them in the Mopar Performance catalog,

a pair each of .007, .014, .021 offsets
