I used 69 Mustang motor mounts because I had them,the 63-65 mounts will let the engine set slightly lower.You will probably need upper and lower control arms and spindle however some of the later 62s have the correct a arms.You will need the strut rods that go with the control arms too.late 62s have the correct ones,ealy models have the smaller units.I bought a beat up 64 Comet 4 door and used it all from steering column to spindles.I bought new upper and lower control arms,They are cheap ,they are the same as a Mustang.Aluminum Radiators are quite reasonable now.I just bought a nice one for $179 ,and its not one with the crappy lookin welds.He also has the conversion radiators with the lower hose on the drivers side for $159.

Here is a link to a lot of my pics.
