Trans Adapters

I rescued these from a scrap aluminum pile today. I know what one is for. Any guesses from you guys that know the real old-school stuff? Or anyone for that matter.

There was a guy looking for the Offy part on another site a few years ago.

Ready set GO! [P[P[P[P

I cheated and found the 3640 for a Lasalle tranny to a Chevy six possible.

The 3640 is for a Ford engine, with a LaSalle-Cadillac transmission.

Bingo! The part number made it easy. Ford flatty to a LaSal/Cad.

One down and three to go.

SG-138 is stamped on the edge of the smaller adapter plate. I couldn't come up with anything on that.

I'm going from easiest to hardest. Picture number 5 is definitely for a GM transmission, but I can't place the engine pattern.
Who had a 6 bolt bellhousing with no starter hole?

I've been watching this thread and searching this piece when I can...







... it appears to be marked "GC-25". My searches suggest "TransDapt" and "GC-25" adapts '55-'60 Pontiac engines to numerous GM standard trans.

I was confused as well. According to the info I found, the adapter above makes use of an "intermediate" housing for automatics... the intermediate housing mounts the starter and the adapter mounts a standard trans to the (iron) intermediate housing...

... I'll post the TransDapt info next... it doesn't fit in this window!

Hey, there we go! Two down, two left.

More Googling...

SG-138 is a Speed Gems item, apparently for early nailhead (264 & 322) to Cad/LaSalle...

Once again, the Doctor rocks! [cl

We can't say I don't have some interesting shop-wall art. Better that than the recycle bin where I found them.
