In my neck of the woods shop prices, $250-300 labor, plus the cost of the gears and any bearings or shims that might need to be changed.

I do it for $150-175 at home for the locals, shims included(I have plenty), they pay for the gears and bearings, bring beer and pizza

Maybe you can find someone working after hours to save you some dough.

Around my area the price runs between $160-$250, plus parts.

With the 8.5" 10-bolt, the carrier designations/case breaks are 2.73-up(called 3 series) and 2.56-down(called 2 series), so a new carrier won't be needed in 79CamaroMatt's case, his has the 3 series already.

8.5" 10-bolt does not use a 4 series carrier like some others do, so 4 and 5 series gears fit on the 3 series carrier.

Although I avoid using them, you can also buy a ring gear spacer to put 3-4 series gears on a 2 series carrier. Sometimes other oddball rearends will require the spacer, as the limited supply of gear sets wont be easy to find.
