This is the metal shift guide that is located on the bottom of the front shift box on all Vanagons that have 5-speed shifters. The 5-speed shifter was only stock on 83-85 Diesel Vanagon or a Syncro Vanagon from 86-92. However many Vanagons have been brought in to the USA from Europe where the 5-speed is much more common, or they have been retrofitted to the 5-speed. You are buying one shift guide. There are two per box so if you want everything to be new, you should order two.
Just to be clear, if you don't have a 5-speed shift lever, you don't have these shift guides. ONLY 5-speed shifters use these.
