which 833 to save ?

I have 3 4speeds...

1 early a-body 833 Ball and trunion w/ 3.09 first

1 early splined A-body

1 early B-body 833

The ball and trunion one has a chipped tooth , broken syncro and badly worn slider teeth.

The B-body one has really nice slider teeth and syncros but has a broken input retainer ,a shot bearing and shift lever threads broken off.

The third is the splined abody which is supposed to be a low mile trany that I will use for my Dart. Yet to disassemble...

Question is which of the first two should I throw all the good parts into ? how much resale on an early Bbody 833 ?
