Technical Packard trans/adaptor/bellhousing question

I received this packard trans with my model a coupe I’m building. I want to run it behind my ‘40 flathead. It came with Lucas adaptor plate, and the broken bellhousing attached. It also came with the hildebrandt adaptor bell. What should I run? The Lucas plate has a lot more material and fasteners, is steel. If I run it, does anyone know what the broken bellhousing is? Or should I run the aluminum piece, it only attaches with 4 bolts threaded into the aluminum.. I’m kinda new to this flathead game. Is the packard trans a good choice?

 

The black bell is a 4 Speed bellhousing, from a 1935-1952 Ford truck.

Shown with a GM pattern adapter.

 

A not broken one: https://www.millworkshotrod.com/pro...s-head-adapter-4-speed-1935-1952-used-1?gQT=1

 

so is this a GM trans or was the Packard trans GM pattern? (Excuse my ignorance)

 

Would there be any reason to not run the Hildebrandt piece?

 

If it fits the engine and transmission use it. Just be sure to dial it in to check the alignment before installing the transmission...

 

I cannot see enough of the transmission to identify it.

The position of the shifter tower looks Packard. I think they went to column shifters in about 1939.

 

That's a Packard transmission. The bolt pattern looks similar to a G.M. pattern, but the bolt holes sit lower in relation to the center hole; in other words, it looks like a G.M. pattern that has slid down lower on the bell housing.
