I didn't fit or source them, I left that to the garage that does my prep work for me, they are called GM autotech in Norfolk, telephone 01379853721. ask for leighton or johnno. they are good guys and have done some great work on my truck. they both own 4x4s and do lots of work on them.
they did have to do some fabrication work for the mounts but the sliders length I think is prefect. I got ones with the holes in for the 110 hilift jack adapter to try and get better clearance on the body when jacking. I haven't tried it yet but it still looks a bit nip and tuck!
they also made me a custom rear bumper that I can hilift on, well actually I could probably tow the QE2 with it!!
we are now thinking of a front one, but I am waiting to decide wether to get a winch or not.
sorry for the slow response, I've been on a jaunt!!
