Parts for Dynavector 501 Tonearm

I've been using a Dynavector 501 Tonearm for about 15 years now.  I have really enjoyed using it, but the arm lift mechanism has worn to the point it is inoperable. I really need parts, or a good machine shop to make the parts to renew the lift.

Do any of you know where I could get parts for it, or a machine shop (close to me in Puget Sound area of Washington State?)

Thanks, and regards,

Dan
