Model T Ford Forum: Forum 2014: Cotter Pin Straps for Top

There was some discussion a few weeks ago about the cotter pin straps used up to 1917. I had to replace the ones on my '13 roadster this week, and I believe them to be original to the car, as the leather was quite rotten, and one side had already broken in two. As I mentioned in the previous post, I believe the attaching screw and washer to be separate, and they are. They are both steel, but this doesn't mean they were not brass plated originally. I could find no evidence of plating on either screw, which is a #7 X 5/8 RH slotted wood screw. A few years back, I had an opportunity to observe an untouched '17 touring, and the cotter pins on it were nickel plated. I don't recall the screws however on that car.

Most of the pins I have seen are brass. Some of screws are brass,some steel.

The drawings call for the #7 x 5/8 screw to be blued steel.

Hello RV:
Wouldn't have a photo of how this looks mounted on #2 bow by chance?
Regards,
Scott

Not the greatest photo, but I only raised the car cover a bit and shoved the camera underneath. The strap is part number T-6837X, "key strap assembly, long." The hole for the mounting screw is 1/8" diameter, punched or drilled 1/4" from the end. The screw hole placement in the upright socket seems to have varied, but on this one it's 6-3/16" from the center of the pivot pin.

There is also a "key strap assembly, short" that goes on the #1 bow. The screw hole is in the same place, but the overall length of the strap is 2-1/4" shorter.

REgards,
