no, the gears will not just swap over.
They use a different carrier. You could probably swap the entire carrier, but depending on the splines of the axles, you may have to swap them too.
why not just take the entire rear and swap the whole thing?

Since your 86 is an open diff and you want to put the 3.73 with the posi then yes, they will fit. The gears themselves won't swap over but the entire carrier can be swapped over.
The 89 should still have 26 spline axles like your 86

Again, better to swap the entire rear axle assembly, housing and all. Easier, too.

You can swap out the gears with the posi carrier. It depends how well you can set up the gears in the older diff. As mentioned above, it's easier to just swap the complete diff.

I cant get my rear end off that why I am going to just swap out the carrier. But do you think that a dirt bike for a whole rear end is a good deal?
