small bolt patter to big?

I went to BBP with my 71 dart grabbing everything including and bolted to the upper and lower control arms from a 73 dart (didnt need the lowers but they were included). Disk brake cars used a larger upper ball joint so you'll need that. I think I paid around $325 for the whole set up and included the prop valve from the donor car. On the rear I ordered a set of axles from Mancini Racing (Yukons) with the 3 inch studs and green bearings installed. What kind of ideas are you kicking around?
