Starter Problem

[CVA59]

Ok guys, I dropped a 78 model 350 in my 64. I kept the original 6 cylinder's 3 speed tranny with the original bell housing. I tried to install the 78 model starter and it won't mount up. Looking at the picture of an original starter for a 64 chevy w/283 & 3 speed. It looks like the top flange bolt hole will hit the block. I have not bought it yet but looking at everything i don't see how it will work. Any ideas what i have to do in this situation???? I did read in another thread on here about this somewhat. However, Something under there just doesn't look right to me. I guess i just need a good nights sleep and look it over again tomorrow, LOL.

Thanks
