I bought a WVO kit from PlantDrive for my '85 TD wagon last fall and now my needs have changed. It's a complete kit, has everything you'll need except for the fuel lines. I also have a custom welded aluminum tank, made specific for W123 wagons. All items are unused, never installed, full instructions included. Selling as a package. Looking to recoup my investment of $2000, buyer to pay freight from 97211. Thanks for looking, links to pics are below.
