not "some degree of modified steering", but
home modified steering components, as in drilling the aging original pitman .... for that matter, where I live you'd have major problems with inspectors over that shortened frame
Johnny, you might find it a bit easier to have a conversation about things here if you refrain from the grade school comebacks, "so there" sure won't work with your DMV or insurance company .... please remember that you're the one who originally said
"It has some MAJOR bump steer. do any of you fellas know the best way to eliminate that?" you've gotten some honest thoughts from folks with decades of experience with these trucks, if you don't want to hear what they have to say, than you shouldn't ask for opinions
