I originally ordered these seat backs for my Parchment interior and was to die them.
After talking to my interior guy, I decided to order the Parchment panels that were not available last year.
New, unopened, they sell for $109 US plus shipping from Classic Industries
You can have them for $ 100 CDN (no shipping)
