Welcome aboard Ian! Sorry to hear about Dad. On the bright side, now you have your kids looking forward to Dad and the car. Great car by the way. Loven it!

There’s tons of old school guys here and some very reputable builders of engines, transmissions, rear ends, a couple of quality electrical guys. Yea! You come to the right place! My suggestion is;

Make a plan and stick to it.
Get the factory service manuals
Ask the local racers (if possible) where a quality machine shop is and hopefully a fella very familiar with MoPar engines as well as an old school mechanic in case you run into a problem or need a special tool that is t cost effective to purchase for 1 job.
Thank you
