Y-Guy Alan: I've done this to my '60 F-100 and Doug T. did his '56? I'll try and dig up some info on this and post it plus maybe Doug
will chime in also.
Very worthwhile conversion, you won't believe how much
better it works!
Think I found something, go to the www.ford-trucks.com
and search for Toyota steering box swap for 1948/60 trucks,
also there was and article in"Classic Trucks" about a year ago.
They used a CPP kit or Mid-fifties kit i believe.
If you don't have all the p.s. stuff, pulley's, brackets etc.
you may want to go the electric p.s. route. It works great and
doeen't clutter up the engine area.(You still use the Toy box)
Hope this helps,
Bill
