I'm working on the interior of my car, a 1935 Auburn speedster replica, and I'm trying to de-ugly the thing (brown carpet, brown velour door panels and awful yellow vinyl upholstery). People's taste in the late 70's/early 80's is questionable , at best. 8) I have enjoyed reading through a number of posts here and have already gained some useful information.

Anyway, my car is a four-passenger model and has plywood bench seats of roughly 36x20 size.

The foam in the seats is not very dense and my 290 pounds places me on the plywood - it's just too uncomfortable after a while, so I need to replace the foam in the seats. I obtained some 2" very dense foam which seems to work well and is comfortable. What about memory foam or gel pads on top? Any experience with those?

I'd also like to replace the simple seat glides with a power unit for the additional adjustment that is available, but the mechanism needs to be relatively short in height. Any suggestions for a useable unit here? I see a lot of power mechanisms for bucket seats and split bench seats, but they are too narrow or wide for my seat and those appear to me to be too difficult to modify.

Thanks.
