JJ is probably very busy with the various wildfires going on right now.  May or may not be a bit of time before he can answer your question...

If I'm not mistaken there might be a couple on flea bay if you're looking for one.

McCuloch Titan 70 piston:compression 23, top of pin to top side 17, total 40. I think a Husqvarna 268 xp piston shoul work instead of the original.

 I just got a Titan 70. I don't have a source for a piston and i was thinking to use a H 268 piston.

i have a titan 70 also, the specs besides the pin diameter are on chainsaw collectors corner. I will be assembling mine from 100 percent new old stock parts soon. If you can to send me close pics of the chainbrake setup it would be a great help. Let me know if you want to sell yours in the future.
