I have parted out too many PH's. I have lost track of what year my frame is. I was going to put a 318 in my truck, but then decided to put a 225 in it. The problem, I sold the steering box for it. I bought one from a forum member, but it doesn't fit, I think is was out of a 48. Since my cab, a 53 came out of California w/no vin tag on it, I checked the frame number and all I can come up with is a 1966 or 1963. Apparently, by reading some of the threads even though they don't address is exactly, not all steering boxes for PH's were created equal. True? Any help appreciated.
