Bolt Size ?
 

What size bolts are used to attach the front fenders, to the inner fenders ?

5/16"-18 X 3/4" Large flange dog point. But unless you buy used ones, good luck. I used the following:

Are these bolts stainless, if not how are they holding up.

Re: Bolt Size ?
 

No they are not. Zinc coated I think. There are some similar "looking" but not large flanges - https://www.flangebolts.com/shop/5-1...ss-steel-22647

Those are nice. They aren't "Large Flange" like the originals, but nice none the less. :)

Re: Bolt Size ?
 

Yep..I used these on my IH...the flange is the same dia as the original IHs were, should have added that I guess...
but I used a flat washer under each bolt to keep the knurles from tearing up my new paint..a 5/16 ss flat washer is nearly the same dia as the bolt flange...

I'm not sure on the washers Rod...the bolt flange is 11/16" and the washer of is 3/4"..
I just grabbed some ss washers...didn't pay any attention to what they were
