You need to come out to CA or AZ and pick up a rust free tub for that thing, as yours looks beyond repair!
Laughing.. yes most people would haul that tub to the scrap yard.. but I will revive it, it definetly won't be a "proper" repair or restoration just as long as it functions and I can hide the repair with custom interior and body work I will be happy.
they do sell the complete conversion kits for the inverted y steering linkage at jeffs..
