Not so long ago, I found a site on the web, where an engineer has a machine shop. I was looking for solutions to a swing axle problem, that resulted in a rollover, and the loss of a 67 bug. Fortunately no one was seriously hurt.
I am guessing the individual has good products, but his people skills are worse than mine. I was told I had no concept of engineering. (But then again, many degreed engineers fit that mold).
Alledgedly, atom***ks has a swing axle conversion, but does not have one for T3s yet.
