Vert tack rail bolts

[Xghobo]

I need 4 of the 1 1/2 inch long with round washer bolts and 2 of the 1 1/2 inch long rectangle washer bolts for the rear tack strips of a convertible, am pretty sure a b or a body area the same hardware?

Merry Christmas everyone and thank you

I just made the rectangular washer out of flat stock for mine if you can't find anything
