I'm a lil uncertain about matching parts as i draw closer doing the chassis for my 65project GTO Clone. While my Tempest has a stock open diff,i'll be using a later year 10 bolt.It may be a 70 or lil later rear that is a posi and i'll be adding a set of 3:23 gears. I've been trying to get a grip on some parts thru conventional parts stores and most importantly a new set of drums and shoes. I see some stores show both a 2" and 2.5" set of shoes.Well,since my diff dosen't have and drums on it,i measured a set i took from a 66GTO and they measured 2.5". Well i came close to getting some drums and thought i'd buy the shoes at the same time. Well now i'm unsure of fit as i also believe i discovered my diff is prob about a 1/2" longer than whats on the 65 now. That itself will add a lil thinking when i try and decide on wheels and tires. Can anyone give me a few details or things to look for to help me do this setup with minimum redo or problems.Appreciate and input.Thanks
