The gear ratios are closer than close-enough-for-gummint-work. Which is to say that you won't see a significant difference in speed vs RPM.
It's definitely worth making the swap if the SPG's transmission is on its last legs. Bear in mind that the '87 transmission has the smaller pinion bearing and it already has a few miles on it. The smaller pinion bearing gives it a bit less longevity than the transmission that's already in the SPG.
What's the problem with the SPG transmission?
