This is an aftermarket version of the 5 speed shifter for 83-92 Diesel Vanagon. It has the plastic tabs on the end.
The 83-84 Diesel Vanagon that were sold here in the USA were all 5-speeds. In Europe from 83-92 Diesel could all be 5-speeds.
Important: You can't turn a 4 speed transmission into a 5 speed by changing the shifter. If you have a 5 speed, this will work for you. If you don't, it won't.
