T10 4 spd. Bell housing??

[karterfred88]

my "wide pattern" (chevy) bellhousing came from an Avanti, according to the person I bought it from. Is this a mistake? or could it be from a 1963 Avanti using parts left over from 1962?

Probably a mistake, as far as I know no Avanti ( R engine) received the Chevy pattern, not listed in parts book, only 1539373 listed which is the Ford pattern. Doesn't really matter anymore. It works better for a 5 speed conversion since all the Tremec TKO trannies use that pattern, but the "input shaft retainer hole diameter" is smaller. At least the bolt holes line up without an adapter.

Remember, the bulk of the "63 Avantis were built in 1962!

It's not unusual for these very old orphan cars to have parts swapped from different models, years and who knows what. I've seen an Avanti with a '61 259" engine and a Flightomatic.

To correct the Studebaker model year information...All 1961/1962 Studebaker 4 speeds were the "wide" Chevrolet bolt pattern. Thus the bell housing was unique to these models. The 1963/1964 Studebaker 4 speeds were the Ford/Studebaker bolt pattern. Thus a V-8 3 speed/4 speed bell housing was the same and common.
This is all confirmed in the Chassis Parts Catalog.

T10 Stude V8 Bells from 1960 to 1961 1/2 +/- have what is called a GM pattern trans bolt pattern, 62-64 T10 bells use a "Ford" style which I believe close to the older B-W manual 3 speeds. All the Stude T10s had a specific input shaft size, pilot bearing nose size and length, different from those in Chevy Ford etc.

[allstateguy]

I might be wrong, but I think <mid-63 was Chevy pattern, after was Ford (Stude). So T-10s came in two flavors as did the bellhousings.

Specifically Studebaker T10 and Stude V8.

[vetteson]

Depends on the make. All Chevy manuals (Saginaw, T10, T5, Muncie etc) have the same pattern.

Are they different than standard V8 manual bell housings.
