Tranny internals - tail vs. Side Options

[kenpolives]

Are there any major internal differences between the side shifters and the tail shifters? My tranny was "howling" and my mechanic said it was the ring and pinion. I had a old tail shifter that looked good but he said that the gears must be matched? and that since these were from the early and late model that they would not work.

Of course he had a "spare" tranny in his shop that he is willing to sell me.
