There are adapters available that bolt onto the VW 205 X 5 pattern drums that then allow the direct mounting of a chevy pattern wheel. No drilling is required. Here's a couple sources: http://cgi.ebay.com/ebaymotors/VW-Bug-Sand-Rail-Wheel-Adapter-5-Lug-VW-to-4-3-4-Chevy_W0QQcmdZViewItemQQcategoryZ43955QQitemZ7992697742QQrdZ1QQsspagenameZWD1V http://www.cbperformance.com/catalog.asp?ProductID=694 http://www2.cip1.com/ProductDetails.asp?ProductCode=ACC%2DC10%2D6705 Why did you post this under the Manxter section? Are these for a Manxter?

A drill jig is a semi-accurate (depending on condition of the tools) way to put a pattern of holes in a part. An adaptor would be a less accurate method. The best way is to use a rotary table on a milling machine to install the pattern after you find the true center so that the wheels still run concentric after they are installed. Any other method is asking for trouble. Tom

I've seen lots of people use wheel adapters on buggies. They aren't machine shop accurate but neither is the O.D of most tires. However,one thing I certainly wouldn't do is to drill a hole through a cast brake drum for a new wheel lug unless there was a thick metal boss cast into the drum, which is designed to support a wheel lug, at the point/radius you are drilling. If you drill the hole through thin metal or too near an edge, your going to have a big problem at the worst possible moment. Adapters and redrilling brake drums both have their own set of problems that the buggy builder should be aware of when they decide what to do. Personally, I'll stick with 205 X 5 wheel centers.
