A common cause for a sloppy or awkward to select gear change on a vintage vw is either the rear coupling is worn or the guide bushes. The coupling is under the back seat on beetles or visable from underneath on a Baywindow bus just in front of the gearbox. This coupling is a new exclusive product by BBT in Belgium, Fed up with not being able to find a good quality product BBT decided to make them themselves with 5 years of development! Copied from a NOS coupling everything about this coupling is best quality. supplied complete even with a new grub screw. You can watch a video here of head honcho Bob explaining about this product. https://www.youtube.
