Wanted: Walker MTGHS remote air cleaner parts

[OldWalker]

Just acquired a 97 Walker MTGHS for homeowner use. Has 780 hrs total time and new 20 hp engine. I would like to retrofit it with a remote air cleaner. (This tractor was manufactured just before Walker began installing them as standard equipment.) I know Walker supplies a retrofit kit (tech support sent me the installation instructions) and I have priced the kit from my local dealer. Does anyone have any suggestions for how to do this less expensively?

Perhaps one of you has a parts mower and would be willing to sell the remote air cleaner parts (such as remote precleaner 7026-2, precleaner tube 7028-1 or 7028-2, air cleaner assembly 5088-12) and mounting brackets in used serviceable condition. Would appreciate any advice you can provide.
