Hello everyone, I am finally getting around to start diving into rebuilding my 1966 Mustang. I have an earlier post about it, but essentially I have a stripped down frame and not a lot of the original parts.

It originally had an i6 engine which I am looking into seeing if its salvageable for use. My question is with having to buy most of the parts including the whole front and rear suspension, drive train, steering rack, etc. can I go ahead and purchase and use the beefier V8 parts even if I drop the i6 back in it? If the original motor is shot, I am going to drop an 289 or 302 in it most likely.

I rather future proof if I can and already purchased an 8-in rear with disk brakes and five lug pattern, with the plan to have disk brakes and five lugs all around. Thanks for the help with this, I frankly am not very knowledgeable and this is all a big learning curve/experience.

I have a 66 inline 6 with 4 lugs. There are many more possibilities for wheels with 5 lugs, but I don't trust the adapters nor want to completely convert at this stage (ever).

SO, my question is , what can I comfortably fit? I know there is a size chart and I don't fully understand it and some say it's inaccurate or dated.

I would like to go 16x6 in all corners. I believe I cannot go to 7" wide, correct me if I'm wrong. Is 16" to large, should I be at 15"?

For context, it is a daily driver, essentially stock suspension (some stuff replaced but not modified), and I would like the most I can get out of grip, ride, and handling. Thank you!
