I am in the process of welding sliders on my 84/pu, I ordered them from 4X innovations..I have welded before but was questionable about welding to the frame and how much I might have to cut the body if at all for the installation..? I plan on using a stick welder and a 7018 rod 3/32nd's for the first pass then a larger 1/8 but same 7018 for the 2nd and 3rd pass..Anyone see any flaws in this plan or maby suggestions? Thanks

i welded mine to the chassi but i plated where they attach with 6mm plate and then added some gussets to beef it upaswell. all done with a mig welder.

i have some old sliders i want to put on my 91 and i was wondering if weld on or bolt on ?

 

yes. ...

 

i agree. weld plate to frame, sliders to plate, or vice versa.
