The 1600 Bug exhaust gaskets are approx. the same bolt pattern and outside
size and shape, but the inside diameter of the hole is larger for the
Vanagon gasket.  In a pinch, I've opened them up by bending them over on an
exhaust port with taps from a ball peen hammer's round end.  Just face the
bent over part pointing downstream so it doesn't 'snag' exhaust flowing past
it.
