It is a big truck cab and has the gas tank located under the seat. I have moved the tank to the rear frame (I am using a car frame). I have cut the top out of the gas tank to use as a seat riser inside the cab like the regular 1/2 ton. I am asking if the one piece seat springs are available or if a 34-35 bottom cushion will work. I do not have access to one to measure it. I would purchase a 1/2 ton seat riser and bottom cushion if available ?
thanks for all the replies, I appreciate the help.
Also although I havn't figured out how to change my signature, I have found a nice set of mercury hubcaps thanks to the generosity of one of the Ford Barn members.
