The driver's seat seams on my 72 RR are separating on my Ember Gold vinyl buckets. Now, there may not be a great difference among these vendors, but I don't know that. So, what are your recommendations, which company would you go with? What about headliners? Headliners, from what I find, are not listed as Ember Gold, but as Lt. Saddle, and perforated vs. non-perforated. Any specific comments? Thanks!
