The problem with cool parts is that they always seem to hit the market right after you finish building your car. In some cases it’s fairly easy to make the swap, but in other instances it’s a bit more daunting. A great example of this is the carbon-fiber wheeltubs sold by Anvil Auto. A few years back they were offered for sale, but only for ’69 Camaros so we didn’t get in on that party. But recently they started selling them for ’67s and ’68s as well. After talking with the bodywork geeks over at Best of Show Coach Works in Escondido, California, we decided that it wouldn’t be all that tough to do the swap and knock a few pounds off Bad Penny, our ’68 project car.
Now, we wouldn’t characterize Anvil Auto's inner tubs as inexpensive. In fiberglass form, they run $975 a pair, whereas stock steel reproduction wheelhouses cost around $170 ($200 a pair for ’69 Camaros). The problem with the stock versions is wheel clearance. In the past, shops like Best Of Show would cut, weld, and fab the stockers to get extra wheel clearance. Of course, that took hours, and time is money. For example, the inners on our ’68 were fabbed to give more turning clearance for our beefy front tires to the tune of around six hours plus the cost to paint, and we didn’t even address the area above the tire. Given this, it’s easy to see how the $800 price difference between the Anvil and stock-styled tubs could be eaten up paying to have the steel tubs modified. As a benefit, the Anvil tubs weigh in at about half of their steel cousins. For a few bucks more, $275 to be exact, you can order the Anvil tubs with the top layer done in luscious carbon fiber. They only weigh a tiny bit less than the fiberglass offerings, but they look “oh so good” since they have been smoothed out, and many of the unnecessary holes were left filled in. So with tubs in hand, we headed over to BOS for some retroactive installation action.
