Finding those 8" chunks is getting harder and more expensive. Which is one main reason I went up to the 9". The easiest way to switch from open to posi is to purchase a complete chunk and bolt it in. You could get just a posi carrier and transplant your gears onto it but it is very difficult if you aren't familiar with doing it. I understand that you want to keep you rear original but some mustangs came with the 9" (K codes). It will be much stronger, easier to find parts, and many more options available, and the prices are about the same for posi units. Down sides to 9" is they are heavier and have a little more drag. A lot would depend on your hp level is.
