1979 camper special

[gstanyer2009]

Hey, I have some questions I have been unable to find and answer on anywhere I go, I have a 1994 gmc I’ve solid axle swapped, with an 87 ten bolt front diff 8.5”. My rear diff is a 14 bolt floater. 10.5”. My gearing is 3.73 in the rear and 3.07 in the front. I want to make both gears 4.10. I know a guy that has both diffs with 4.10s in it, will the 4.10 gears fit into my 8.5 front and 10.5” rear? The donor diffs with the 4.10s are out of a 79 Chevy camper special. I have half ton running and the camper special is 3/4 ton but the guy that has the 4.10s says the rear is 14 bolt 10.5” and thinks the front is the same as mine but could also be 9.25” but he said that shouldn’t matter because the gears will still fit into my 8.5” front diff. Does anyone know if that will all fit or not? Really needing an answer lol
