Brad, this sping I started My restore on a 52-3100 and You do not have to pull the steering arm to remove the box just remove the 4 or 5 bolts holding it to the frame and turn it as you are sliding the colum out of the cab , rusted bolts I use rust free and than a impact with a 6 point impact socket if it a smaller bolt or nut I turn the air pressure down a little if it does not move, go one way than the other . I have started to blast all My small parts using a blast cab from Grainger than I paint them with Rust Stop primer from Ace and than paint with Rust Stop top coat the color I need ,it takes alot of time but now I go in the garage and see fewer and fewer parts all rusty and boxes of painted parts ready to install when the time comes {no time soon} Have fun, Pete
