[VintageLambo] Countach QV Floor Mats

Hello all, I am in the midst of reconditioning the interior of my QV. I have a good start on the leather goods inside with some Leatherique products (highly recommended!) and have removed the seats for that job. Two questions: 1. any advice on lube for the seat adjustment rails? 2. The original floor mats (jute backing) have become very stiff. Is there a good way to limber them up? I nearly bought a set of "new" ones on ebay, but couldn"t take the red bull insignia on them. Are there other more "correct" mats available still? Also, just to follow up a bit, I found a significant battery drain coming from the installed Alpine stereo system AND the trunk light. thanks! David
