You are correct if your guess is based upon the current assumption that LOS cars and Norwood cars had identical VIN's by date, which in this case would make the car a very early 69 car (August 68) and of course then most everything could be wrong -even the cowl hood. There is only one problem with this theory on VIN dating it is also currently believed that only 25% of total camaro production originated from Los Angeles, so using the Norwood template- concurrent VIN to date ratio could be skewed by up to 75% error using this assumption.
Assuming the car is August 69 build - then the engine is correctly cast. Has anyone/organization conclusively made heads or tails of Los Angeles month to Vin/production yet? I agree with JBB on at least a title search prior to purchace unless you happen to be a wizard with numbers, Broach marks, and identifying a restamped parts. The Re-stamps that I have looked at over the years are pretty obvious.
