Re: 69 BB Hood Insert fit question
Ed------
The difference in the 2 sets of part numbers was the speed nuts included in the second set. The moldings were the same, at least for any given time. The GM part numbers 3922285 and 3922286 appear on all the moldings, PRODUCTION and SERVICE.
I fully expect that PRODUCTION and SERVICE moldings were absolutely identical, at least if they were both manufactured at the same time. So, I expect that PRODUCTION and SERVICE moldings were the same during at least the 1968-72 period. Sometime after that time something changed. Why, I cannot imagine. I just can't understand why the molds would have changed. It's hard for me to believe that GM would have invested in a new set of molds after the moldings were SERVICE-only pieces and the mold change couldn't have happened prior to the end of their use in PRODUCTION or GM wouldn't have been able to install the moldings on PRODUCTION hoods.
