JEEP Owners! 1995 KGC with rear latch broke?

One report said the latch breakage was typical. Said that the only way to access it to repair was to have it opened! Since it is shut, they had to drill a hole from the bottom of the door, then unlatch it, then drill out the rivets, remove the latch, and replace it. How much would a dealer charge for this??The latch is $24.00 on a Jeep Parts lists. Anyone have this done??
