How do a 070 and 660 piston compare

[Nutball]

If anyone has a 070 and 660 piston laying around, I'd like to know if they use the same size pin, and if the pin to crown height is similar. I know the bore sizes are way off.

Different pin sizes 12 bs 13 mm

Thanks, that shouldn't be too hard to fix.

Now I just need to know how much the height difference is (roughly)

I have both of those saws but not an 070 that's apart.

Can someone measure the height of a 070 piston relative to the pin (pin to top and bottom)? Thanks

And the exact diameter 57.xx
