  • Hole size for 1931 side mount spare

    Can someone tell me what is the correct size hole for the grommet that goes in the splash shield for a side mount spare tire bracket? The service bulletins have it listed as an 1 5/8 inch hole, but this is for a 28-29 car. Is it the same size for a 1931 160B? Thanks

    I tried to place some dividers through the grommet in our 160 B, and it was a little more than 1 1/2" though approximate.. The vendors' repro grommets fit if that helps, though the bracket (round portion) needs to be exactly centered in the apron hole for the grommet to fit properly.

      Thanks Plyfor, so are you saying that the inside diameter of the grommet is 1 1/2 inch? or the hole in the sheet metal is 1 1/2 inch?

        Ed: Just had a chance to peel back the grommet on both mounts. The actual shield hole varies slightly on each side, but the average diameter is 1 9/16". Would suggest having the (repro) grommets before doing the holes if that's possible as a cross check so the grommet covers the hole completely. We ordered an extra because they can tear when trying to force them in the holes (with the arm in place and if the hole is offset slightly).

          Thanks, I will drill holes in a scrap piece of sheet metal and see if it fits.

            THEN place the grommet in boiling water and let it soften. then insert for fit...Do that with a test and the final one also

          So I drilled a practice hole with an 1 1/2 inch hole saw in an old licence plate and the new grommet would not go in . Thanks for the tip on boiling water Mark, that dose make it much more pliable.But, then I started thinking, with the compound curves at that location of the splash shield, the hole saw blade should create an oblong hole as it penetrates the steel. First I used the cork trick to mark where the center of the hole should go, Then with the 1 1/2 hole saw, slowly drilled in reverse to make the hole. Sure enough, when the hole was complete the grommet slid in rather easily. Thanks again to all for the help.

            What is the "cork trick" you used to mark the center of the hole location?

                  Shackle hole
                  by davew
                  I have to replace a shackle on the front. I saw a video where they said to drill the hole in the shackle bolt all the way through. The shackle I have the hole only goes part way in. Will this weaken the bolt? Also supposed to grind slots by the holes to hole more grease. Thanks

                  Vapor Lock/Carb Design?
                  by Paul
                  Too cold outside to do real work, I thought it would be a good day to strike a match.


                  Quick question, you who experience vapor lock do you have an early carb or a later carb? The later carbs have a vent hole in the bowl. Is it possible that customers of the time complained to Ford about the flow of fuel and his fix was to vent the bowl. Just curious, some people experience this...

                  Question: Model A wheel bolt hole pattern
                  by Mickey
                  How is the bolt hole pattern measured? It's 5 hole and looks to be 3 1/4" between holes. Is that it?

                  What do you think?
                  by Mickey
                  I found my answers.

                  I have new sheet metal for most everything but am finding just how poorly some of it fits. I spend a LOT of time trying to get the new metal to fit and even then I'm not sure it's right because I have so much removed and can't be sure of correct fitment. It's got me rethinking discarding the old metal, some of it is repro. but fits perfectly. The new rumble seat mount...

                  The 1928 Cylinder Front Cover
                  by Steve Plucker
                  This concerns the attachment hole to the front cross member that is on the passenger side of the cover. Does the hole go through the cover or was it blocked off when the part was cast?

                  I kind of think it was blocked off but not sure as I have just one of these and it is an open hole...

                  Thanks.

                  SIDE Mounting Spare Tire ?
                  by Cape Codder
                  Has anyone ever seen a SIDE Mounting Spare Tire Plate with BOLTS instead of STUDS to hold the spare in place?
                  I have checked Brattons, Snyders and Bert's for this type of mounting but found none. Is this a non-existent part or someone made it?...

                  Marking location for side spare carrier
                  by Beauford
                  There might be better methods but I like the KISS mode. Go under apron with a ole can of primer and shoot up carrier hole. (Make sure apron is lined up correctly first)
