Got forked

Mike,
The bell O/A length for a stock bell housing is 7.380" per MP Chassis book I do believe. If the bell you have is shorter, it can be an issue for pivot height if the pivot mounting boss/pad does not compensate for the difference. On my old LW housing, I needed to add a 1/8" to adjust for the block saver plate. An old Ansen plate I have is even thicker.
BTW, It appears to me your new pivot is like the one in the pictures I posted.
