47RE swap (photo ID)

TrailBeast said
Speed sensors can be removed and replaced with the standard 904/727 speedo housing and gear.
You do know an RE trans is going to need a computer or shift controller, right?
You could end up needing that speed sensor so don't get rid of it.

Trail beast: I was looking at this speed controller to manage the RE

COMPUSHIFT Mini for Chrysler A518/46RH and Chrysler A618/47RH

I added one picture of the bellhousing. Does it look like the 340 LA bolt pattern to you? Do you know if the register or “nose” on the tourqe converter lines up and will fit in a Scat crank shaft (pn#9-340-4000-6123). I will measure both before purchasing it but at the moment I assume it is the 1968 larger size.

Thanks
