yes, those parts are non existant, don't come with a new MC either ... some time back I took the banjo to NAPA and went thru all their stuff and faked something that worked, but failing that you'll need to find good used, a post in the parts wanted here might turn something up
and welcome to the garage Hugh, always nice to see another TF series [pictures, we love pictures!] - there's some folks here who may have what you need, and always lots of good info
