I did not want to spend close to $200 with any of the venders for two running board mats for my '48 Tudor Super Deluxe, so I sourced the rubber myself and made a killer pair for less than $55. I don't mind spending money for quality stuff, but I hate to waste it. I ordered a 2' wide, 1/8" thick, 4' long weatherproof piece of corrugated rubber (Item # SN-750) from American Floor Mats, Rockville, MD for $31 with $15 shipping. I got a tube of waterproof automotive adhesive for rubber from ACE Hardware for $9. I made a cardboard pattern for the driver's side and flipped it for the passenger side, and the running board rubber mats came our perfect. I also have enough product left over to make another set if needed down the road.
