bigsky4ever, is your an LA plant "E" code built car?
ns1rm21's (Troy) Swinger is a LA built car. Big difference on those cars is the black type primer they used underneath the cars as opposed to the grey primer used at the other assembly plants.
Thats correct.
Black undercarriage on LA built cars.
In the resto thread for my old 340 Swinger, I have pics of the original primer, and after I recoated it.
