I have front seats and a fixed rear bottom seat from a '51 HJ.
They are the rolled and pleated brown Dragon vinyl option, only on '51's.
The front seat has a few ripped/torn areas; the rear seat is in great conditon except for a tear near the bottom.
The pic of the rear seat shows an area that I have cleaned.
The circular area on the left side of the front seat pic is a reflection.
Additionally, I have a fixed rear seat back with all the stuffings.
I am tendering offers for the seats complete w/frames...
or..
I can remove the covers...
or..
whatever!
Considering that replacement Dragon is $85/yard, this is a great start.
