Power Steering setup - what tools do I need?

You could unbolt under the dash and back the whole column out of the way. No key, no problem.
You'll probably need that box coupling with the swap. There is a tiny pin just under the cap that holds the guts in it. So forget feckin with the 1/4 dia. split pin for now.
I think I separated the exhaust Y pipe at both exhaust manifolds and shifted it out of the way to get the steering gear out from under my 67 w/LA. Take along a hack saw just incase?
I think I needed extension and universal to get on one of the gear box mounting bolts buried in a hole but the universal may have been for impact clearance. Pliers for the one cotter pin, gloves safety glasses... Good luck
