I'm looking some help regarding a cracked housing from my 79 thats getting a frame off resto ATM. One of the PO had hit something hard enough to crack the housing and has had it welded up. The housing also has a steel ring adjacent the cracked area. Check out the near failure on the axleshaft (the lower shaft is from my K20). Have any of you guys repaired then run a housing for any length of time? Is that steel ring factory? Its not on my K20 D44. Im a little hesistant to use this housing long term and even tough its a major PITA, I'll swap it with my K20 housing before is sold. I'm very worried a crack will propagate accross the case.
