talk to the guy
eBay Store - Great Lakes eStore: CDs, Records, Other Formats
on ebay at that link. They parted out a 69 last year and only put the big ticket items on ebay, but have a lot of the misc parts still at their shop. I managed to get speakers and bathroom light lenses from him. His prices are a little high but takes offers. Don't bother emailing him, he rarely gets back to you, just call him on the number in his listings.
It reaffirms my thought this afternoon while hooking up gas lines that I should put a safety cable with a caribeaner in case it comes loose going down the road that it will just dangle, but can be unsnapped and removed for service work.
