How do I remove my driver side seatbelt???

I'd say any repair shop should be able to replace it. They could possible fix it too. Unaffortunately if you do need to replace it, you'd have to get a used unit either from a wrecking yard, a II parts supplier or other mustang II gurus like us who may have good used units.

**If you need to aks for one, remember to post in the Parts part of the MII forum!**
