I am attaching my switch panel on a 24, and do not have the hardware to attach the switch panel to the dash. Ive searched and found they should be an oval head slotted screw, but i cant find what size and length, or what goes on the back side? (Washers, nuts, etc.)
Could someone tell me what these fasteners are supposed to be?

This is a 19-22 dash. These are #8 oval head by 1/2" long with square heads and no lock washer. I would have used a lock washer. I would think this correct for your '24.

I pulled one of the screws off the switch panel of my 1924 cut-off touring, and once again it has incorrect flat head phillips screws in those locations. The screws were fastened on the back side with 8-32 nylon insert locking nuts, which are also incorrect.

That said, the phillips screws are 8-32 and 3/8 inch long and fit well, so I searched through my boxes of screws and found four 8-32 oval head slotted screws that will work once I cut them down to 3/8 inch length. I'm going to keep the nylon insert locking nuts because they don't show. :-)

Jake, go with the 1/2 inch length that Richard says. 3/8 is a little too short, especially if you are going to use lock washers. Luckily, after cutting my first screw to 3/8 and finding it to be a little short, I was able to find a fifth screw and cut the rest to 1/2 inch.

I wonder how many more phillips screws remain to be found on my car? At least these weren't metric like some of the others! :-)

Dos anyone know the size for holding the amp mater in the switch housing? This one the length is very important.

#6-32. The one I measured was a little over 1/4" long. Again with no lock washer. A lock washer may be good to use but it would ride on a slot rather than a hole on some ammeters and might be objectionable.

I believe the oval head slotted screws I used on my 1923 are 10-32 x 1/2. I used split washers too.

#10's are tight in the hole. They probably would work ok but the heads stick out and look big. I would go with #8's. I believe they are correct.

The screws that hold the switch plate to the dash come in the interior screw kit that we sell
