I have a folding rear seat with I guess a trap door from the trunk, the seat does not fold at the hinge, think its rusted solid and hear what sounds like plywood splintering when i try to force. Also I need new door panels, are there panels that will cover the entire door inside? Will seats from a 03-04 cobra fit? I have a floor console (4-spd)and the door is gone, do they make repair kits for these things?

I've seen rusty hinges, but never so rusty they wouldn't move. Is the seat up or down now?

No. The door is textured, if it looks bad you'll have to use paint stripper and naval jelly to clean it up. NO SANDING! That will destroy the door.

Will seats from a 03-04 cobra fit?
Not without modification.

I have a floor console (4-spd)and the door is gone, do they make repair kits for these things?
The 67 & 68 (not the same) console 'garage doors' are available new.

 

I agree, even though I am not familiar with those seats. Start by putting some "liquid wrench" on the hinges if they are rusted up. It will help break them free. Next get a buddy to help you out and have them start to fold the seat from the inside with NO FORCE. You look from the other side and see exactly what is going on to prevent it from folding. It sounds like something might be caught or wedged in the way.
