I was reading an older post a few weeks ago on how to use a bright colored crayon and rub the area by the oil filter with it then scrub lightly and remove the excess crayon to reveal the partial vin. It worked great! I cleaned the area with acetone first a few times to remove all paint and was still not able to see anything. Then I tried this method. The first attemp with the crayon exposed a N and a 2. Then I worked the crayon on the area agiain where I saw the numbers and put it on very heavy then took my time with a new tooth brush and was able to make out 1 9 N and 5 out of the 6 numbers of the vin sequential number. The motor is in the car and I was told it would be impossible to see the numbers with out the motor out of the car. i would recommend this method to anyone who has not been able to read there partial vin on late 1969 cars.
Also this helps prove that a March 29th build DZ 302 can be original to a early August build car. My car is a 08C car and could have been built during the second or third week since 08B was skipped. I also talked witha few people who suggested that because productionwas not extended yet dealers were not getting many orders for Z28's with expectation of thge new 1970 Z28.
Don't you mean May instead of March?
Yes I meant my engine is a May 29 date, NOT March 29th, sorry too many dates to remember.
