I'm building a 30 Closed cab (non-exteneded) pick up and have a question about the seat. I want to keep the interior somewhat simple, going with stock dash with minimum of guages, roadster colum with 40's wheel and want to keep a simple seat. Due to the lack of space in a PU I was thinking of going with a stock seat riser and spring base and building my own back out of 2 Inch highdensity foam. I would recover the cushion and back to match. My question is has anybody got a better idea or is there something I could be missing. Your thoughts would be appreciated.
