I have an original deluxe interior. On the back portion of the rear seat, the 90 deg. stiched seam that goes from the top corner to the white inset trim has let go. I assume the thread has just rotted. I talked to a local upolstery guy who told me he can restitch it with no problem, but this will create more needle holes and perferations in the fabric and the fabric will eventually rip away from the seam. This does make sense to me, but what else can I do? I want the seam restitched, but I don't want the original interior compromised by the material ripping. Maybe he's just covering his rear end incase it lets go? Any suggestions?
