Noleen crosslink shock alternatives?

[ishaw]

I have a nice fork, I know that risse do a shock for the fork but recently saw a fork for sale with a fox air shock that looked fairly standard.

Does anyone know what alternative shocks might fit the fork? If so, which, and what modifications might be needed? Lastly, if an air shock will make a difference, good or bad, to the forks performance?

Thanks.
