JVC QL-7 Tonearm Questions

I recently purchased a JVC QL-7 turntable on eBay. While the table itself is in incredibly good condition the tonearm appears to have two issues:
1. The rubberized spring mount for the counterweight droops.
2. The cartridge does not sit vertically when viewed from the front.
Has anybody had an experience resolving similar issues wil the Ql-7.
Is the arm worth keeping or can someone recommend a suitable replacement arm for the QL-7.
