I agree with Fred T a 73 thru 87 C10 will work awesome on the 58 thru 66 and its a easy install I bought one to install on my 51 but my frame is almost 2" to narrow and was told that its a perfect set up on yours because the frame is the same width as the 73 - 87. just drill a few hole and bolt it in !
Good luck
Todd


Some people are like Slinkies, Their not really good for nothing... But they still bring a smile to your face when you push them down the stairs.
