Shouldn't need to do any of what you said...not acording to my instructions
they only need to be welded if your fitting them for competition...they supply a lug that gets welded. (there is a seprat part on the instructions for the welding if your fitting for comps)
it shouldn't fowl on the donut if you brought the right guard they have more than one rear guard for the disco. one for the donut and one without. I dont have the donut anyway I changed it for the UJ
Any way I will let you know
