This gearbox was in my '89 full size Blazer, 4x4, it worked ok, but I thought it was loose, so I changed it with an expensive aftermarket one, but there is still a bit of looseness, so it wasn't all that bad.
Since i bought it online, there wasn't a core charge.
So if you want a decent, but not tight gearbox, here ya go.
PM me, thanks, Jeff
