I looked into the PUI covers. When i asked the ebay seller about wheather they had the buttons or not, he was unsure and stated that if I wanted "show quality" , this was not the product to buy.
I thought that was an interesting comment and appreaciated his honest opinion.
I'm not able to comment personally as to the quality of any of the products currently out there. When I did my first three Skylark/GS restorations, there were no aftermarket seat or door panels available. I was fortunate to find NOS fabric/vinyl including the ribbed insert panel on the back of the front seat.
For the next two , I personally sewed the covers after searching down the correct white. At the time, the current manufacturers used an off white. When placed next to the original door and quarter panels , the samples looked yellowed.
Unfortunately, the aftermarket stuff is less costly then doing it myself.
When you consider the costs , my opinion is that the Legendary product looks like a good deal.
Just an opinion, for what it is worth. Maybe nothing.
