Just installed welting on my 1.5 ton GMC. 1946. Had to buy 12' from Steele just do from the running board to where the inner fire wall sheet metal starts. About 2 feet on each side as original. Looks great but pricy. Fenders are the same as smaller trucks except the opening for the 20" tires so welting is the same. Let me know if you want a part number.
