Looks good Al. Did you snip the little wire tensioners off the T studs? I asked because I recall from my first rodeo, a spot where the end of that wire peeked out a crack between two pieces somewhere. Where grille meets headlight surround maybe?
I forget just how far off standard oversized the OEM nuts were. Standard 10-24 nut doesn't capture enough header panel so I used stainless flat washers and nuts.
A couple years ago I was working on something around here, I forget just what but it was outdoor related. Anyway... It was assembled with some oversized/heavy wall nuts made of nylon. It occurred to me that those would serve in this application without a flat washer.
I never did look around Lowes or Home Depot to see if they were available off the shelf.
