Black 396 air cleaner lid

[Mr70]

Sorry,my last reply shoulda said the P&A 1969 parts book dated 3/1/69 for Vette/Impala/Truck that calls out CHROME for $8.15 on page 3-39.
Based on what John said,that makes sense,as they were likely reflecting the latest design which woulda been the chrome finish for the 427cid. 66 Vette.
Maybe there was more of a design difference with the #356 vs. #832 lid then just chrome vs. black,based on their different part #'s,specific model applications & prices shown...while both offered at the exact same time too.
I'd like to see these two lids next to eachother.
