the 68-72 A-body K-member has more room for a kick out pan than the spool mount 73-76 A-body K-member.
So we wanted to point out the pan does work (really close) with the 73-76 style. Those K-members have columns that support the spool motor mount and narrow down each side of the K-member’s U-shaped opening for the oil pan.
I think the wording should be changed to 67-72 and 73-76 A-body k-members.
I’m not sure if they modified the pan for more clearance since the first ones. They did borrow a 73-76 K-member and new NOS motor mounts a few years ago to “check things”
I think it would be a good idea mock yours up when using a 73-76 K-member or just clearance the K-member like 72bluNblu has pictures of.
Again 67-72 A-body K’s have plenty of room.
The Milodon SB pan will work with 67-72 A-body K-members
