Duster seats

regarding the frame 70-71 same, 72 is on its own

I heard that too but I've also heard it said that 70 through 72 frames were all the same

Anyone have evidence of either opinion?

Has anyone ever matched the plastic seat back screw locations from 70/71 to 72?
From what I understand 70 plastic backs are shorter and a bit wider? correct me if I'm wrong.

I have a set of 72 buckets but what I really want is a pair of 70's for my 70 Duster, so I either need to trade my 72's for 70's OR if the "70-72 frames are the same" opinion is true then I can just recover with new 70 foam, covers and backs from Legendary

Lets hear the evidence for either.........Sale at Legendary ends 1/11/16 Tic Tock :clock:
