drive shaft question

The boots are readily available, as are the complete rebuild kits for this pre-'66 ball-and-trunnion front U-joint -- the boot is not year-specific -- from Andy Bernbaum (he officially supports Mopars only thru '62, but the joint kit and boot listed for '60-'62 Valiant suits all pre-'66 A-bodies). But in the long run, conversion to a cross-and-roller front U-joint is definitely the way to go. It's a totally standard procedure any decent driveshaft shop can do; see here.

The Neon boot make-work is a clever fix!
