Re: Seat
I am somewhat the same build & wound up buying a seat from a junker, removing the covers (not hard) and reshaping the foam for a wider derriere and increased seat angle (if I can't recline at least 30 degrees, my back hurts.
Can even use some spray glue to add lumbar support. The once you replace the cover you have a seat that looks stock but can be driven for hours.
Can get even more drastic if you have a coupe. I think they were designed for elves.
