If your mutt is an A2, this image could be worth it, it would be 31, 32, 36, 37 (2 units) and 38, they are in the manual 218-34P, figure 93 and then the references, those of the A1 are on the previous pages.
My advice is that you learn to see the manuals, I am restoring a complete A2 and if it were not for the manuals I would have gone crazy ... once you find the exploded view you just have to see the references and google them to buy them. a greeting
