Go with the 87!!
Hey Ron,
I see yours is a 86 year car.
Previous knowledge on the Forum here is the 85-86 tranny was revised in the 87-89 years and the usual 5th gear failure was re-enginnered out? Perhaps using the 87 would be a good move all in all for you?.
If your going to keep this car for many years, you might want to keep the old tranny.
When I took my tranny in for a rebuild, I needed a new differential. I took my old tranny over as a donor and the labor bill was only $200.
Although you might look at $50 for the core, perhaps having the parts available for another rebuild will be well worth the $50 investment.
Remember you have no history on this new tranny, if you need parts you'll have them
Just a passing thought bro.
BTW check that old 86 disc carefully, if it has rubber balls in the center think about going to a newer disc with double springs if you can find one used.
If you think the 20 yr old rubber is still viable give it a go, odds are it on it's way to decomposition.
