Question Trans swap - bellhousing compatibility question.

G'day all.

Currently have a 1967 C10, Saginaw 3 speed behind an Inline 6 250.

I plan on swapping out the trans for a NP440/MY6 A833 4 speed overdrive trans out of a early 80's truck - the trans I'm buying is the standard GM mount, and not the Chrysler/GM hybrid.

What I need to know is, can I use my current bellhousing from the 3 speed?

Reason I ask is, my truck is a factory right-hand drive truck, which means my clutch fork is on the right side. The bellhousing that comes with the A833 is from a LHD truck, so it's clutch fork is on the left.

Can I use my current bellhousing, or will I need to find another alternative (custom, etc)?


Thanks for your time.

Cheers,
Russ

Re: Trans swap - bellhousing compatibility question.

I did a little searching since your question got my interest. I have the same engine and transmission and have kicked the idea of installing a 4 speed on mine. Here's something of what I found on this site and this article which may or may not help: http://www.customclassictrucks.com/t..._transmission/

GM called it both A833OD and NP440. The RPO # was MY6. There were two types of the trans installed in the trucks from 81-86. One had the same bolt pattern as any Muncie, BW, or Saginaw and would bolt up to a standard GM bellhousing if you turn down the bearing cover. This is the one I have and it's bolted to a '621' bellhousing. The other had a specific bellhousing because the bolt pattern. It looked like the one on the left in this pic.
