i think the old truck will be running a rear steer box that will cause more than a 2 hour delay when putting in new front steer components and a new steering column---there will be a new hole through the firewall and the dash may have to notched for the column-----i would plan on an average shop spending a week on it----but then a backyard ratrod outfit might be able to punch it out in 4 hours because those guys have been through the 12 step program enough times to know that 2 steps work best if you tear the bandage off......
