Looking to replace the original seats on my 69 vert. The saggy front seats could be rebuilt but the lack is recline angle option is the deal breaker. Trying to keep the seats with a similar period style. Found some inexpensive Procar options but are there others to consider? A functional headrest is the only other requirement. Here's the Procar model I'm considering: https://www.speedwaymotors.com/Procar-80-1300-53L-Pro-90-Seat-Driver-Vinyl,319102.html
