I think it will work as a drop in as is. No needing to cut the base.

I am not the most accurate person and I do not have super pricey digital calibers but this is what I got.

compared to meteor stock 066 piston.  (IIIII)

pop up around measuring across 33.30mm

bore 53.96  (53.96)

height to squish outer  42.85mm (43mm) and to top of pop up 43.75

pin top to top of pop up 17.60  (17mm)

Not going to pull down my 505 just to test this piston (just got it back together with stock 505 piston in it on 1st tank still).
Anyone here have a 066 660 505 2083 that can test and compare numbers to a stock piston?

These pistons come with high performance chrome plated rings. They will only work with nickel ceramic coated (Nikasil) cylinders. All OEM and NWP cylinders for this model chainsaw are Nikasil coated. Some aftermarket cylinders are chrome plated. DO NOT USE in chrome-plated cylinders. ENGINE DAMAGE WILL OCCUR

Will do.  Have 2-Farmertec PC, 1-Cross MMWS PC, 1-Raisman PC.  I like the Raisman PC the best of all.  Have the MMWS on the other 660 have to pull it back down didn't relieve the (Hyway little thicker skirts)piston enough it's hitting crank throws.  Any thoughts on which PC to use?  Used Hyway piston wCross MMWS cyl. Have 2 660 kit saws. 
Looks like Ebay seller is moving them.  He is in Tiawan probably buys them for $10.00 or less.
Hope my random posting is understandable. LOL It's late blame the Moon    shine.
