Restoring 1969 dodge dart GTS after 24 years

Well after 24 yr's. of owning my 69 GTS its time to get going on this. You will see in the pictures I have started on it. Now I am running into some questions that I am looking for help. First question is about the trim strip that I am seeing on other cars on the bottom of the car from the bottom of the fender and goes back to the bottom of the qtr. panel. Should my car have it or not? My car has the original paint and the fenders has a what looks like an 1/8" hole about 3" from the bottom of the fender but no other holes are in the rocker or bottom of the qtr. pnl?? Does anybody know what code I should be looking for and where do I find it???
Next question is on the build sheet the number for the engine is what i think is 027 I can't find anywhere what does that mean??
Thanks in advance.
