Those look right but it is impossible to tell from a pic. Do they tighten up well?

No. The teeth slip. So they are too narrow. Someone on another thread told me that their's were phillips head. I have some phillips that will fit, but do I need washers too? Seems like I do.

use stainless steel phillips round head screws get ones that fit youll be happy at the result and they wont rust

Washers yes.

I just put in my stainless screws with rubber washers. Cleaned everything up and installed my wipers. Need to wiper blades. Other than that I'm happy with my progress. Next up, button up engine and when I'm done with deadlines I'll weld on the rocker panel stud flaps on the body. They rusted off.

Man you are flying along on that thing! Excellent! Where do you find the time? <{:^)

I don't know if I"m flying. I started it last august. Don't even know if it runs. We'll find out! REALLY need to get this welding done.

Today I jack up my driver side rear tire, clean up and grind out where my rocker mount is supposed to be and weld in the new one. Wish me luck!

BAM!! Not bad.

Anyone know what size nuts go on the studs to hold on the gas tank?

10mm with a 13mm head

Hmmmm. Grabbed 10-24 and 10-32I and neither are threading. Hurrrm

those are standard
try 8mm or 10mm what looks close to it
in the tiny metric nuts

Hmmm... even M6 is too big. Heading back! LOL

I can't get my filler hose back on my gas tank. Don't really want to buy a new one.

Do you have some digital calipers? I would have tried that, measure the inside diameter of the hole then go see which metric bolt was about the same, adjusting for thread depth probably a millimeter or 2.
