Its harder to make sliders than side bars Aust.
Why,
Sliders need to be mounted of the chassis in order for them to be "true" sliders, easier said than done.
Hard to explain but here goes. They should be at least fixed to the chassis in three places, back/middle/front.
The chassis runs parallel with the body of the car from the back mount point to the center mount point. Then from there the chassis tapers in towards the front center of the car, If you have a look you will no what I mean. Much harder (but not impossible) to do than side steps which you can mount from the original location.
Would be interesting to see a few underbody pics of bubbalucci's to see how ARB have mounted them..... buddy old pal
