I have a Linde H30D with the two stage simplex mast. I am looking to replace the two hoist chains with aftermarket chains. The oem chains are over $1200.00 for the pair, which i think is crazy. I have been trying to find aftermarket chain, with no luck due to the plastic guides that are affixed to each link of the chain. Normal BL chain will not work as the guides on the Linde chain serves two purposes, 1. It provides a valley for the mast side shift hoses to ride in. 2. It provides a valley for the mast roller. If anyone has any advice or knows where there is aftermarket chain, please let me know. Thanks !!!!!! Brad
