That is a common part that didn't change much throughout the years. Any place that sells front end parts can get you some. Classic Industries or PST who are vendors here. NAPA and Rockauto as well.
Just to show what they look like. Those are different than on my 66. Those have a groove that fits in k member . As I said they are advertised as correct for 65. Bought a rebuild kit for my 65 and it came with ones like my 66. They didn't look right, the ebay ones I posted looked like they would fit better. Rock Auto maybe OK for larger orders, shipping on small orders high MO. Went to order spark plugs with shipping they cost more than parts store. Driving to part store costs money too so it's a wash I guess.
