68 RS has the shorter ww moldings. All 67 and standard 68 are full length.
I don't think they're any more valuable than standard moldings....maybe to the right person, I guess. It's pretty easy to cut standard moldings to fit RS.
I'm thinking 250-300 for the pair ??
edit; btw, it's not unusual to see 68 Z's , non RS, with the short rear ww moldings....Chick's (aka 68camaroz28) included. I asked him about it, he asked Jerry and was told it's not uncommon.....
Pretty certain I got that right, maybe Chick will drop by to verify... :yes::thumbsup:
