170mm left crank arm, black, similar to or compatible with what came with an '06 Trek 4300. Square taper. The original left arm wasn't tightened properly from stock, so it wallowed out. I replaced the crankset with something nicer made by Sugino, but wouldn't mind getting a replacement part if someone has it, for spares.
Stock seatpost from my '01 Schwinn Mesa GSX. I think it's a 26.8mm post, I would have to measure it to know the length. It's shorter than the Bontrager post I swapped it for.
I realize that the chances of someone having that exact crank arm and wanting that exact post are rather slim, so if you need anything else let me know and I can scrounge the parts bin, I know there's more stuff in there.
