Is the width of the 31 RPU the same as the 31 Sedan... I have a '66 mustang and I could swear that my seats measured 22" or 44" for the total width and I measured the Sedan and didn't see that they would fit.... I think a set of Mustang seat frames with new padding in them would be fairly comfortable in the sedan...
