Schumacher SB to BB Biscuit mount not fitting

A little, but it doesn’t improve clearance much. After turning looks less than 1/8” movement. I saw on another post someone had Schumacher measurements I haven’t seen before. I’ll check those and see what I get.

I wonder why the pump is so tight to the mount, every photo I’ve seen from cars on this board there’s at least 1/4” from mount to rear of oil pump. Mount studs slightly incorrect?
