Whatis the best method for shorting a VW bettle pan?

ie straight accross, angle etc etc?

Also best welding technique?

Any tips for the alignment process?

Is this vehicle going to be registered?

If the car is intended to be registered as, for example a dune buggy, you need to talk to an engineer before you do anything else.

Modifying any vehicle chassis, which includes shortening a VW body pan, causes the vehicle to become a NEW CAR.

Be careful. You could be about to walk blindfolded into a registration nightmare.

See an engineer.

well said. Didnt think you were able to shorten pans anymore.Most fiberglass body's available now are for a standard wheel base I think..

You can lengthen a car, you can widen a car, but you cannot shorten a car and register it as a modified vehicle. As shaihulud said it becomes a new car. This means it has to comply with ICV and current ADR's. You must see an engineer before starting or you may end up with scrap metal.
