Not sure if this is where you send in a question for “Dear Welder Series”, but I’ll ask anyways.
Glad you wrote, Drew. This is exactly the kind of question we deal with at DWS.
Your truck would use our 60″ Mustang II kit, Drew. Other front end parts can be used from a “dead” Mustang II (1974-78) or 1974 – 80 Pinto. The hot rod aftermarket has everything brand new, too. Just get parts for 1974-78 Mustang II and you’ll have the right things. The 1979-92 T-Bird power rack is a good choice if you plan on power steering. Stock or dropped spindles can be used with our kit.
Welder Series has a disc brake kit, http://www.welderseries.com/
I hope this helps. You will likely have more questions as your research continues. Please ask us. We want to help you have fun with this project.
