Slant 6 Gurus...Another "What's This Bracket From?"

I know this is an engine - to - trans support bracket from a /6, but which engine/trans combo? Automatic, 4 speed, 3 speed, 4 speed od? Years? Models?

have one like it on a 69 Dart slant 6 3 spd

Goes on the lower side of the block where the oil pan meets the block....Driver side.....mates the block to the transmission bellhousing....had one on my 70 Dart Slant with a 904

Thanks guys, I know where it goes. I'm wondering about specific applications - I've seen some that were narrower top to bottom with a shorter distance between the rear bolt holes.

That looks like a stick one. The automatic ones are flatter.
