Yeah... I hear ya on the fabric thing. And like you said the seats will be stripped right down to the frame so no worries in the mold department.
I just caught your video. It was cool to see an animated version of the ol' '49 revival. Exhaust sounds good and looks clean too. Nice car Dave... and nice work on getting 'er back into shape.
Btw... LOVE those two horns under the hood. Bet they sound good too!!
