Anyone know if the bottom foam for an f series bench seat would work on my 74 bench seat? CJ pony parts sells it, for about 200. Thinking fixing up the bench seat would get me through the next few years, and free up time and cash to spend on other issues. I found a split bench seat cover for a similar amount. 400 or so, and I'm done. trying to keep the budget for front end parts, wheels and tires.
