Need information on GM manual bellhousing?

I have a GM Aluminum Bellhousing that came off a truck Cast # is 6263756. Can I use this on my 1962 Impala with a three speed transmission? I am doing an engine swap going from an in-line 235 to a sbc350. I found this bellhousing at a swap meet for cheap but not certain it will work. I do know the hole is larger then it should be but I believe the bolt pattern is the same.. Is there a filler ring made to retro fit this?
