Replacement Seat for JD 5105

[lincmercguy]

My JD 5105 has an aftermarket seat (not a great one) that needs to be replaced. I don't necessarily want to buy all of the expensive factory parts to make it stock again. It seems like there area all kinds of aftermarket seats available online, but there is very little mounting information. The mounting spot on this tractor is at a forward angle. I'm also curious what aftermarket brands/sources are good ones.

Thanks!
