One Year Only Stuff 67-72...

[casper1969]

I believe the rear tail light trim option in 67 was the eye brow only where as years after were the whole light trim and only top bar for tail gate trim where as following years had the bottom trim as well
1967 was only year 283 available
1969 gmc the only v6 option was the 305 they discontinued the 351 v6 after 1968, although special order was still available til early 1970 for the 351
1967 had no big block option
