The Small Car mount fits the 3.3L Subaru engines and we have a design for Vanagon 2wd or Syncro. Our mount features a support for the muffler so the exhaust assembly moves with the engine reducing exhaust system flex and breakage. Our adapter comes with the hardware to bolt to the Subaru engine. You will need to have the stock Vanagon rear crossbar and new rubber mounts are recommended. We add an extra rubber mount location in the center for a total of five. Required using the smaller 4 cylinder oil filter.
