PUI seat foam?

I have a set of 72 buckets(and the medallions for the rear seat) that I also wanted to recover as 70's but when I threw that out on the forum many members said they are different.

I think the 72 seat stitching looks better so I'm just going to use 72 front and rear upholstery in my 70 might make a purist or two mad but it's a restomod
