At SAAC #34 I took this pic of a trunk mat that was in a '67 shelby, [noticed the stiching in the corners]. Question #1, Were all non rubber mats done this way originally regardless of plant or time frame? Question #2, What dictated what type of mat you got [rubber, plaid or speckled]? This is in regards to 67-68 mustangs and shelbys, thanks.
