1) Check the differential case. The early 420s had two bolts holding it to the cross member that attached to the frame. When the frame flexed it sometimes cracked the case. They later went with a one bolt slotted design because of this. My case was cracked but had been welded.
2) Early 420s had a front PTO tensioner that was attached to the side of the frame. It's kind of hokey and make sure all of the parts are there and it works.
3) In 1983 the steering column was a 4 port instead of a 5 port. The big difference between them was how the fluid got to the steering column. On the 4 port the fluid went through the H3 valve first and on the 5 port it went to the steering column first. hat can happen is when lifting an implement (like the front blade) steering will become less responsive .
