help with Thorens headshell

anyone know where I can get a tp50? or is the "removable" headshell standardized so that any would work?

i have a Td135 and the removable headship completely covers the cart making alignment nearly impossible - plus it just looks far far far too old school for me.

i'd like to put the Thorens tp-50 on, but if I can't get my hads on one - anything that would fit, i'd consider.
thanks
