I've seen some people swapping the rear seat bottom cushion pretty easily, but has anyone swapped their driver seat? Did you replace the whole seat or just the cushions? There are some gen2 cushions on eBay that are in good shape and pretty tempting. But I can't find any video instructions or description of difficulty. Would it be better to buy the whole seat rather than the bottom and top cushions? No matter what I try I can't seem to get comfy in the seats, no upper back and shoulder support. Also lacking in the thigh area. Hoping the gen 2 are better, and it's worth a shot for me. Thanks in advance.
