There are photos of upper cowl painted body color(boss9. Kk) and they were produced January thru July so depending on when your car was made during that period would determine if the upper cowl was body color...since I believe they stated painting the upper cowl black towards the end of the model year. Maybe looking at shelbys built during the same period may help
I have a few boxes of NOS AF32 Autolite Spark Plugs from 1969/70, boxes marked C9ZZ-12405-A. These are New Old Stock that sat in the back of family owned auto parts store since the early 1970’s. From the Autolite Spark Plug Master Catalog they were OEM for 1970/71 Boss 302 and Boss 429. Also 351 4V and 302 4V, during 1970-71.
Asking a fair price of $4.00 each.
I also have a few AF42 C9ZZ-12405-A, and others same vintage. BF32’s are sold.
I can't find any part numbers on them, so any help is appreciated. Thanks in advance. And they are for sale, please inquire if interested, $750.00 plus shipping.
