MGB Overdrive

Somebody can help me! I found an overdrive coming fron a MGC. Is this can be installed as direct fit on 73 MGB ? It’s a RH one.

I’d try MG specific websites for this question.

Being unfamiliar with the MGC, I looked it up. It seems to have been a 6-banger model based on the MGB. Whether the OD is compatable I was unable to determine. It may take some searching.
