i havea a 1972 bench seat i plan to have redone and i wanna have new foam installed and i was wondering whats the best foam to use ?
Agree, upholstery shop will have it. If you are doing it yourself, look for POLY FOAM made for auto or marine use. There are online supply houses. Here is a link to one that has a decent stock of foam - https://www.albrightssupply.com/default.asp
