Besides having a model T, I also have a 1929 model A p/u roadster. I have the four 10-32 x 1/2" screws to mount the instrument panel. However, the "D" nuts that are attached to the gas tank for the two lower screws are missing. Have not been able to locate any replacements in any vendor catalogs. There are slots/cut outs in the gas tank for what is missing. Would like to used the correct mounting hardware. Thank you for your help.
Les, go to Snyder's online and search for d-nut. The first item shown is binned as a 10/32 nut. it's really a 10-32.
A & L used to carry them. I'm surprised Snyder's doesn't have them, maybe give them a phone call.
BTW, the repro dash panels usually don't fit well.
Also before you install it the 29 dash panel was originally SATIN nickel, not shiny (one of my pet peeves). You can satin a shiny panel by using a buffing wheel and 180 grit polishing compound--goe easy, it doesn't take much, the pattern is horizontally across the front, follow side to edge.
Oh, "cinching" the nuts in may be very difficult, maybe just use JB Weld to hold them in.
Maybe use a clip nut:
