My uncles race car has a saginaw power steering box. It is a 70 chevelle. I was curious if the ones used on the 71 to 73 mustangs were the same. Will they line up to the holes for the box on a 68 or do i have to drill some holes and such. I really dont want to deal with control valves and cylinders so im looking for something simpler, like a box that has the power steering lines going directly in it. Otherwise im gonna go with a j car rack setup. Im really not downs for spending 1700 on a aftermarket rack. its a straight 6 to V8 so its a b**** sometimes. Im 21 with a part time job and full time school so it comes together piece by piece.
