I had about 8 hours just in taping off the grill on my 72. Lucky for you, the 70/71 grill is much easier to tape. Also, the 72 grill is molded in grey so I had to mask it twice.
I know the 71's are molded black, not sure about 70.
I found some touch up rattle cans from advance auto that were a really good match. I can get the info off the cans this evening if you want it.
