classic parts are selling it but its not cheap: https://www.volkswagen-classic-parts.com/catalog/en_uk/part/051105255A?ct=3&q=051105255 you could probably use the earlier one with a spacer behind it I guess?
Ah i wasnt sure if it was 051105255 or 051105255A, they seemed different from the pictures. Ill bite the bullet and buy it
Nearly got it sorted, need to buy a new v belt since this one is worn down. Also it seems that it is hitting the waterpump pulley so I'll make some small spacers. I bought some unmarked pulley from a yard sale and it fits the crank pulley perfectly, incredibly lucky. I've attached a pic, adjuster screw needs to be shortened. Made my own since these aren't being sold anymore
