3 Generation Project
Tubs are 14" now. I didn't really measure how much I widened them. I followed the standard recipe pretty much. I cut the tubs down the middle. Then cut out and trimmed the inner half and moved it right up to the frame rails. Then added a strip down the middle.
I just took the seat frames and tried to fit them. Marked where they were hitting the tub and then got out the cut off wheel, hammer, giant pliers, and welder and adjusted them. Didn't take too long.
