Search for 'Williams' in 'cycling' in 'sporting goods' on ebay every now and then, and you'll find another spider. Alternately there are many other chain rings besides TA that will fit; my preference would probably be Stronglight. The outer rings are 151 mm bcd, as I recall... not that this really helps you! Very cool crankset.
It is 151 BCD. I'd take any spider that would fit.
