The 58-60 MEL (383-410-430) has the same bell pattern as the FE-sergent wrote:
Ive read on other posts that this block is an incomplete fe pattern, but will it still mate up? I would not think missing one bolt would be a big deal.
The 61-65 LINC (430) has a modified FE bell pattern. No interchange unless an adapter is used.

The 66/68 LINC (462) has a dual pattern, the previous HX and the NEW LINC SPECIFIC C6.
