Just noticed your posting was over a year ago, and I suspect you may have already found a roll pan. If not I have a n.o.s one hanging on my basement wall. Was going to use it on my ’61 Cutlass, but didn,t need it. The front roll pans are different between the ’61 and ’62’s, but the rears are the same. Might want to add however, the rear pans are quite time consuming to remove and replace. GM loved to spot weld. Lol.
