The groove is in the drum, not the case.

I've swapped the 5-plate direct clutch drum into a regular case without issue. The retaining ring groove is in the iron drum, not the case.

Note that rebuild kits all come with 5 plates, but you install either 3, 4, or 5, depending on which type of direct (third gear) clutch drum your tranny came with (groove location in drum determines this). I'm pretty sure the cases don't vary if the drum is different.

I believe most car and pickup C6s came with three clutch plates in the drum. I suspect more plates may have caused a harsh shift into third, so three was settled on as the standard.

M-7044-A is the old Motorsports part number for the drum, and C9OZ-7D044-A is the factory replacement part number, both obsolete. The part is still sold new at tranny specialty shops. I paid about $90.00 for mine a decade ago.

JMO,
Shoe.
