Had to ride in the back seat (GASP) of MrsCrzys LE the other day. Don't ask, we had a carload and thats how it worked out.

The backseat where the sun shines on it is sun rotted all the way to the base of the foam. The part where your head would rest.

Does anyone here know a source, place anywhere I can easily fix this or would it be easier to find a replacement seat?

replacement is probably easiest.
