These seats were done by SCARLETT AUTO INTERIORS in Topeka Kansas.I was sent to them thru Alain. The cost for these in leather was $1200.00. That was a far cry from the $3000.00 I was quoted in this area. It was a little concerned with shipping my buckets out to someone I never heard of before but Alain gave them a good reference. I have no regrets.Oh by the way there tel. # is 785-234-2966.ask for Gary. As for inflateable supports, I did not put them in.
