A quick question, Lugnutz. With the nearly 1/2" difference in thediameter of the bellhousing center hole, do you get a ring machined to put over the input shaft retainer to take up that difference and help center up the transmission.
Bells that are earlier than (1968 maybe?) have a 4 + 11/16 center bore. The later bells were 5 + 1/8” and reducer rings are available.
