Actually the 86 has 4:10's and my 1995 has 3.42's. I am looking to swap the whole diff because with new front ring and pinion and parts to install and labor will be about 715 vs 275 to just swap with the 86.
What's different, the actautor? Or the ring & pinion size? I Thought that they were the same(electric actautor in newer models)until like 1999 when they switched to plug-in type pass. car CV shafts. With the exception of the ZR-2 and highriders having Fullsize IFS ring&pinion and wider track width.

1985 S-10 4x4 Soon to have 3504BM/TH350/D44/14FF, 35" Boggers
Not real sure on that. All I found out is they are different part numbers and the 1995 was about 120$ more. Dont know what that got you though. I am getting the ring a pinion from the 1986 so I will let you know if they were different when I get them swapped in. I just hope they work now! Well see.
