TR4/4A AAAAUG! anybody got an extra TR4A piston?

[Banjo]

I was cleaning up the pistons I took out of the TR4A block, and I picked a big chunk outta the parts cleaner pan. I thought, wow, that ring was broken.... no wait... that's a ring land! Crud!
I guess that goes with the marks I found on the big end of the number 2 rod. Looks like a PO in the distant past tried to extract that piston without taking the ring ridge off the top of the cylinder.(The head was removed when I got the car) I took them off yesterday in prep to remove the pistons. I was being very careful because I planned to use the pistons for my rebuild.
I'm betting the noticeable play in the crank bearing on #2 was causing a good knocking noise, and was probably the reason the engine was pulled out of service.
All this to say, now I need a replacement 86mm piston. Stock fare for a 66 TR4A.
Anybody? anybody?

Some time ago I purchased a set of connecting rods (off ebay) and these were on them. I'm not sure if it's a TR4 piston or 86mm, but I have a set of 4 that I will not be using.

-Funny thing, I ended up not using the connecting rods either. My pistons were rusted solid to the liners. I eventually used a sledge to drive them out, and found the original rods were more 'balanced' (closer in weight) than the ones that came with these pistons. I used new liners and pistons and had new small ends pressed in and reamed by a machine shop. IF you want these pistons, let me know.

That may just be it Jerry.
My screen is a bit dark, is that reading 85.46mm?
I'll double check mine, but I bet that's it.

If Jerry's piston does not work let me know I got one that measures about the same. I can't throw anything away.
