i was going to use coach bolts to put my radiator armour back on, they look identical to rivets, infact if you were picky you could bash the bolt head to give it the abused rivet look. the big advantage is of course nuts and bolts are easy and can be removed and refitted as many times as you like, there's also the cost to consider as 200 coach bolts will cost you about £50. the down side is you will be able to see the nuts on the inside but don't worry if you're at a show and someone starts to critisize your nuts just knock 'em out, put 'em in the drivers seat with a tin hat on and say it's part of your display
