The limited budget is the killer, but there are ways. On the front end, get a crossmember from a 73-83. To install you need to drill some new bolt holes.

Rears are also available at local yards. Measure the distance between the drum faces ( where the wheels bolt on) so you get the right width. Any 2wd from 71 on will be 5 bolt lugs, which will match the front crossmember. I'm assuming your 64 has coil springs on the rear, and the 73 and on rears will have leaf springs. This will mean either converting to leaf or having the correct spring mounts welded on. A good junkyard can help a lot here, and should be able to tell you what gear ratios are available. Shoot for something in the 3.42 to 3.07 range for a driver, depending on your engine and tire size.
