I'm sorry if this is a bit Off Topic. I need to purchase a new signal light lever CAM for my 66. Mine broke and it no longer kicks back after turning. I searched a few places but they only sell the whole assembly and it's about $100+. Seems like it would a $5 part.

Can someone recommend a place (or website) I can purchase one from?

There are 2 different turn signals for your 66. You need to look at it and see if it is a Guide or BPC part. You will find the letters BPC cast in the plastic or Guide. You must know which one you need. GM # for BPC is 387115 and Guide is 911051.
