So, yeah. I'm looking for the spec of a OEM piston which will fit the bill for a future project.

The problem with piston that comes with the hyway kit is that the piston is short (in order to clear cases). I'm after a suitable 54mm piston with 12mm wrist pin OD with longer skirt, since I'm happy to clearance at the cases themselves, and having the long skirt gives me more options re. porting.
I did consider the stihl 066 piston but it having 0.060" ( ~1.55mm ) too high pin to crown measurement, kinda makes that a little tricky. If you take a quick look at this post:
#34 you'll see what I mean.
So I'm wondering if there's a suitable Husky piston I should maybe look at for this project. Any of you guys know of such a piston?
i.e. 54mm bore / 12mm pin / about 15.3mm (0.609") pin to crown
