Nobody reproduced the original standard 1968 seat covers, only the deluxe or SS. The phone representative spent much time sorting thru this with me. Only my front bench needed replacing so I for the 1st time tackled recovering the seat with the deluxe covers. Only problem I had was not realizing that there is not 14 gauge wire included with covers to go around the lower perimeter. By time I figured that out the old covers were in the trash. Fortunately the hardware store had 100’ of 14 gauge galvanized wire for 8.50. Everything went well after that. I will be installing the rear covers tomorrow. Couple of tips from my limited experience. 1. Put covers out in hot sun or warmest part of house for a couple of days before installing 2. If not able to stretch covers under seat tight enough to attach hog rings.at locations rings will go, use 12’ black wire ties. Leave loose and work back and forth to slowly pull material tight to attachment points. Then can add hog rings and leave wire ties if want because they are buried under the seat. 3. If any wrinkles when done, use a clothing steam gun to heat up and work wrinkles out. 4. If almost perfect, walk away. It will finish stretching tight on its own. I’m no expert, but this is what worked very well for me. Quality of the covers was great, no complaints.
