73 bucket seats vs 69-72

[BurnoutNova]

i have some 73 blazer bucket seats, and my original medium green buckets from my 71, and the 71 buckets need recovered, but there not that bad. so what i was wondering is are the 73 buckets the same as my 71 buckets?becasue if they are i want to just leave the originals alone, set them to the side and get the 73 buckets redone in black and maybe if they ever start reproducing the right shade of green i need redo the originals.
