Where to get VW Service Tools for Gearbox? 318/15 and 381/14

Any ideas where I can get these?

318/15 and 381/14

Haynes says i can use an exhaust clamp, but i assume cause mine has been sitting for a while (gearbox), I now just have a broken exhaust clamp and the adjusting ring is in the same place… :huh:

Cheers
