nice pick up. 27k is well bought. re suspension and sliders, I have a bilstein package in mine and it is such a good ride on dirt. amazingly well controlled and great on the blacktop too. With the lift you'll need to be aware of your cv angles and not go too high or slip in a diff drop crossmember to keep it all working well. I've gone with a 2 inch lift and the diff drop. HD efs torsion bars and ridepro medium coils in the rear. the bilstein package was sent upfrom Autocraft in melbourne and fitted up here. Darren @ Autocraft custom valves the bilsteins specifically for the 100 when putting together the kit, you can buy the longer shocks anywhere but the valving will be different. he also does a scmick long travel kit if you wanna get super slinky.
I've recently fitted a set of Powerful 4x4 sliders, they've gone together well and seem solid. had to modify the passenger side one slightly but only elongating the bolts holes a few mm and grinding a few mm of the top of one bracket, it wasn't clearing the floor, maybe the 11 year old body rubbers have crushed a bit but it was easier to mod the slider than replace all those rubber blocks.
