SS/B Barracuda project

Thank you, and no hurry tho... the "A" and "B" measurements, and width "C" and depth of the seat. With your help this seats are going to look awesome. And has to be. They are such a specific feature of these cars, and must look perfect... Now if I only can make them look somewhat used. Or the one on the drivers side that is... May be put it in my old sexiest something Volvo Tractor Loader. As a matter of fact it has a Bostrom seat in it, a lot heavier though, but quiet like it :)
I did contact some of the firms that sell farm equipment, but on luck... but like I say, with your help this project really is heading in the right direction... And who would believe Volvo could contribute to a project like this any way :)
And again, I appreciate any input and comment as I move along.
Still waiting for two brackets that need to be made, square tubing's that fit snug in the brackets of the rotisseries...
