I thought this was pretty cool. I've questioned in the past when did NMW transition from the generic tow tabs to the chassis specific ones. Here is a September 1969 article which features NMW TB28 tow tabs for a 1966-1968 Mustang.
Anyone know or feel differently about items such as early Corvette TB3 and 1967/68 Camaro TB9 <span style="font-weight: bold">NOT</span> being manufactured before the TB28s? I would guess that publishing in 1969 usually meant you actually had the magazine layout done about 3 months prior to print. I am comfortable with the idea that chassis specific tabs were around by early 1969. Maybe some of those early Part Numbers were even out in 1968! They look pretty darn nice too!
One other thing, anyone have one of those cool "Super Street Cars" Magazine decals for sale?
