guys, just answer his damn question.
if you have the turntable heel piece still intact, just search around for a cheap pair of px15 or px18 (or axial equivialents) and then just use the toe piece. No matter what the din is, all p series toepieces are compatible with the old turntables (notice I said "p," not "px"). I have a pair of p12 turntables and found the px toepiece that they came with to be too light and thus created a weight imbalance that caused me to grind rails on my heels. Unhappy with this, I found someone selling some cheap px15s, grabbed them, and then just mounted the toe piece (which is still the original "p" toe piece) to go with the turntable heel piece. Didn't matter that the toe was 15 and the heel was 12, they're both set on 10 and that works just fine for me.
