I am not clear on if the rear spindle support finish. I have seen two cars and one guy at one NCRS meet told me he got deductions because he had them painted black and another who had points deducted for them being natural. I do know that there is machined areas where the shock mount goes through. Can someone clarify. Thank you

Re: Rear spindle Support
Keith----
I'm certainly not the definitive source of information on this subject, but I'll relate what I know.
According to some, 1963-67 Corvette rear bearing spindle supports were painted semi-gloss black after casting, but before machining operations were performed, in a manner similar to the finishing of brake calipers. Therefore, the supports should appear semi-gloss black, except machined area which should be "natural"(or "natural rust" within a short time after machining).
For 1968+, the rear bearing supports were supposed to have been left "natural" cast iron and unpainted.
All that I know for certain is that the spindle supports on my original owner '69 were definitely unpainted. I find it curious that although the trailing arm assemblies were unchanged throughout the 65 to 74 time period, GM discontinued painting them after 1967. It certainly is possible, though. Most of the suspension components on GM cars of that era were unpainted, so, perhaps GM decided at some point that they were wasting money on painting of the bearing supports.In Appreciation of John Hinckley -

Re: Rear spindle Support
What Joe tells yu sounds right. One thing I'll add is the judging manual states that the rear spindle castings are painted semi gloss black. If a judge feels that that is not correct, he should let it slide cause the manual states otherwise.Comment
