Dimension of stock rear end

Thanks for the feedback. I read the article on 68Cuda.com and he had some good things to say about the Ford 9 inch. It also is a banjo style housing with a removable "pig" or center section.

I found a Ford 9 inch for $100 with 3.54 gearing and open diff. I am thinking it may be less expensive for me to buy this, have it narrowed and transfer the bracketry from my existing rear end to it. Rather than spending the next year looking for an 8 3/4 for a resonable price. It's unbelievable what the 8 3/4's are going for.
