Don't let a bit of shaky grammar or spelling chase you from this site. We have done hundreds of V8 swaps into AD's and so have others so all the information you need is available on the "search" function. I hate, HATE the fact that Chassis Engineering has closed shop (owner died) as this was a one stop shopping site with very reasonable prices. Do a search on "265 exhaust manifold in a 47-54 Chevy truck" and you will find the engine can be centered, nothing moved, and shift linkage will work. As far as a rear end do a search on rear end widths and look for one close to 61 inches wide; this will be given as the wheel mount flange to wheel mount flange (WMF). Early Nova rears were dead on and had leaf springs but are scarce now. We use mostly Explorer rears now but they require a spacer or wheels with less back spacing plus cutting off all the non leaf spring brackets. They are tough, readily available, and cheap. This swap is so popular that a factory installed look is easy to attain. I have heard, but not used, that a Colorado/Canyon rear is very close for fit and has the six lug bolt pattern---check it out.
