Husky 55 closed port/Dolmar 5100 maybe echo 5100 piston??

[sawgarage]

Needing to replace a couple... from my understanding the dolly 5100 piston was almost 100% cross compatible with the H55 closed port @ 45mm...

I see on HLS's site there is an echo 5100 piston listed which is also 45 mm, anyone know the specs on this piston?

Thanks guys!!

only piston i know of is the little red barn one.... have used a couple with good results... saws still running.... both fire wooders...
interested to know though if the dolly would work for future reference....
