No one knows? brrrrr Well these trucks are approaching 100 yrs old.. Its probably harder and harder to find the answer. blush This subject is crossing the older thread but different so I will explain what I am doing. I am custom welding an old seat frame to fit bc I didnt like any of th alternatives and this cab is small.. front of the seat is only 43" width.. back wider.. anyway once I add the foam and put it together; not sure how Im gonna attach it to the tub base on the '38.. maybe drill holes and hog ring it.. but really curious how they did it factory! headscratch
