John, I talked to terry today and he told me about your dilemma. When I restored terrys seats, the legendery sport seats did not have a horizontal listing pocket stangly enough.So I just atached the vertical listings as I normally would. When I tore down his original seats the horizontal listing at the top of the seat really didnt do anything anyway( like pull in the horizontal stich line area of the seat). My best advise to you would be --that if you have the old foam -gage your cut to the original( use a serrated knife).Its a tricky thing to get proper placment of the cover to the foam -- Too high placment , even an 1/2" off will throw off everything and eveness can be frustrating as well.Make sure you heat up the covers before install by either a clothes dryer or heat gun. BUT DONT walk away from the dryer 3 - 5 minutes is enough in most cases, you dont want to ruin the covers and if using a heat gun dont get too close or stay in one area too long.Believe me , Ive installed and reinstalled and reinstalled again and again on some seats utill I get great vertical and horizonal seat lines. Hopefully this helps and I made some sense. Good luck.
Scott
