Hello Grumpy,
Had a look at the manual, it is not for a 8/30. The 8/30 has a H pattern gearbox, 3 forward and 1 reverse, but best guess the rest looks pretty much the same. I would think most parts are the same and if nothing else is available may do the trick. I looked on the ID plate for the model number but it has faded away over the years. Thanks again for prompt reply. Keith.
