I believe Rick is on to something with that observation. It's hard to say what percentage of 80s will be going to enthusiast 3rd owners but for certain, those that have lockers will be the quickest to sell; simply because there are a large number of 40/55/60 owners that *know* these have the diff lock option and as those owners add to their stables and/or move up the the 80, they will be insisting on the F&R diff lock option. The prices may not go up much but I am 100% convinced they will forever sell quicker with the diff locks.
Another reason is that the current "drive-out" price for an installed ARB system, front and rear, is $2500 to $3000. This is not likely to go down while the prices for used 80s will continue to go down (at least to some bottom price.) For those that want lockers, adding $2,500 to a $5,000 vehicle is much harder to take than adding $2,500 to a $20,000 vehicle (used 97 prices a couple of years ago.)
