I got a roll bar from a short box Chev,arced the mountpads off,cut the tubes down 3" I believe, ( it has been awhile since I did it) in a cut off saw,rewelded the mounts on, had it powder coated flat black,positioned it in the Blazer,marked the holes in the mounts and drilled and bolted it down,On the bolt that holds the uprights to the top cross over tube I mounted the hanger for new shoulder harness seat belts from Mothertruckers.The short portion of the belts mounted to the existing holes,but I had to use a couple pieces of aluminium angle.It turned out really well,I will post some pic,s of the Blazer soon (frame off restoration/customize ) Regards
