I noticed my 1950 chev truck with a 261 was missing in the bell housing the fly wheel pan. I ordered one on eBay (see picture) and I quickly placed it on the bell housing and it seemed to be a perfect fit. So I degreased it , cleaned it , sand blasted , primed and painted and went to put it on and the four holes on the pan do not align with the four holes on the bell housing . But interestingly two holes on the passenger side align and the pan seem to be centred over the flywheel. I am thinking of simply drilling two new holes on the driver side and see what happens.
But I must be missing something as the part is apparently for a 1947-1953 chev or gmc truck.
My original transmission was the sm420 and I replaced with a t5 but that shouldn’t have anything to do with my situation ? Can anyone enlighten me?
