Well I got at it today and got it in! Woohoo. It was a bugger though. I put the upper part in place and let it drop down lower than where it normally sits, then used an oversized flathead screwdriver to turn the lower in line with its slot, then while keeping it aligned I used a balpeen hammer to tap it up into place. I tested the spring before putting it back but man will I be pissed if my weld breaks. LOL
