As far as I know, the only way you can do a locker in the front is by swapping 3rd members with an older Sidekick. Hence, you won't find many ppl with lockers in the front. There are a couple that I've seen on here or other posts, but that's about it. I'm hoping to do the conversion within a couple of years, but front and rear conversion with ARB lockers will probably cost $2000-$3000.
