What size of screw are supposed to be used in the footman loops for the front and back bows?

Oval head?

I just had my originals out. They are either a #8 or #10 oval head slotted, steel. The length is 1".

The Ford drawings specify that, for use on the footman loop used with the leather straps, the screw is a #7 x 1" "French (oval) head slotted blued steel wood screw." Drawing date is 10-17-13.

For the loops used with the woven cotton straps, it is a #9 x 1" screw, same specs. (Drawing date 8-4-19).

Thanks guys. I was able to find a #8 x 1" oval head slotted in brass. Good thing I have some black paint... I might try to re-size the head a little to a appear as a #7.

I have some #7 oval head screws, but they're brass and only 1/2" long. They should be OK if you're not screwing into end grain and the wood is good hardwood. I can send you some if you want.

Oops--hold it--I believe I do in fact have some of the correct #7 screws. I just have to go dig them out. Let me know if you'd like some.

Who is ever going to check your foodtman loops to see if there is a #7 screw in it? If a # 8 will bury itself in there, then use it. I know that sounds weird coming from me, but there is a lot of strain on those footman loops, and you want all the contact you can get. #7 sounds awful small anyways! If you guys want answers, I'll be happy to take one out of the '13 roadster I'm working on, which are original, but I'll guarantee you they aren't #7s!

The chart I have says the head of a #7 Oval wood screw ranges from 0.268" to 0.305". The #8 screw ranges from 0.292" to 0.332".

The #8 screws I found had a variety of diameters. Most were 0.812". A few were larger, so I turned down the heads of the larger screws so they all measured 0.312".

Who will be able to tell the 0.007" difference? If anyone does, I'll call the screws #7 ex-size.

So what is the measurement of your screws, Larry?

#8 screws look right in the footman loops. Be sure to use a steel screw, not brass.

I'm pretty sure that the screw size has to do with the loop. I believe that the earlier loops used with leather were forged or cast, while the later ones used with cotton were stamped out of sheet steel. The later stamped ones have larger diameter pockets for the screw heads.
