I just replaced the door checks on my '31 S/W Town Sedan. I used the Bratton's 32840 arm set and the 32910 arm pad. The old pads were dried out and fell apart. The new ones from Bratton's easily replaced the originals with the two screws provided. The new arms replaced the cheap repo's that someone had used. Now have three settings for how far the door will open. Makes a little easier getting in and out of the front seat.
