Rodger,
Try contacting swayaway axles (they are on the net), I'll bet they can set you up. The axles on the car are definately VW as the porsche 914 axles were too long. The VW axle slide into the 914 CV joints. Swayaway sells axles for different vw/porsche conversions, sand rails, customs etc. Would be really nice if your solution was just a knowledgeable phone call away.

The car's been done for about a year and half. Well, they are never really "done", always some new wild idea to set in motion. The rear hubs were built from a 914. We did not build the dedion tube, that was fabbed by Thunder Ranch. The engine in the pictures is in the process of being replaced with something of better quality and more power. No death wish. Just love to roll on power. angela
