I have 2 1971 front grills. There are 2 long very small diameter bolts that holds the grill assmebly togther. I am pretty confident that these are 3mm diameter but I am struggling with the thread pitch.

Does any one know what the thread pitch is for these bolts and know where I could possibly about them?

Thanks

Most 3mm bolts are 0.5 mm pitch. I have a couple of old grills that I haved used for parts in the past, I'll look and see if I have any of those bolts. Do you need the ones in the center or at the ends?

An alternative may be to get some 1/8" brass or soft steel rod from a hobby store or such and thread the ends for #2-54 nuts or something like that? Maybe someone like McMaster car has 3mm all-thread!!!!

just checked. Sure as heck McMaster car does have 3mm all thread in steel, brass and SS none the less!!!. 1 meter long in brass is $12.69. That place is amazing.... Just search for all thread, then look at the low strength. They probably have it grade 10.9

I used 3/32" stainless steel all thread that I bought at a local model railroad shop.
