K1 140mm Cranks

I bought a Koxx trials and the seller had been riding it hard with the cranks loose. The hub seems to be in decent shape, I put a pair of Qu-ax ISIS cranks on and they fit tight. I really want to replace them with another pair of K1 140mm. As long as the both ends are in working order I don’t care about cosmetics. Please let me know. I’ll be travelling starting tomorrow for a few days to my daughter’s college for parent’s weekend so feel free to email me at sailorcrew@hotmail.com rather than a pm. Thanks very much, David.
