I have a 1967 camaro and want to buy a seatcover kit for the front and rear seats. My question is the houndstooth kit was not offered in 67 only in 68 and 69, will it fit my 1967 seats?

I don't know if Houndstooth is Delux interior only, but if it is, then it seems the 67 & 68 foam seat buns/cushions are different. That could be a problem..?

If the seat buns are not the same I would think that if the frame is the same dimensions that the upholstery shop should be able to add or take away to fill the void. I am wondering if the dimensions are the same, does anyone know? Thanks guys!
