67' cars had the RS or SS badges on the front "nose" of the cars fender in front of the side lamps would be on a 69' (no side lamps until 68). In 68 they started to use the engine displacement emblems(327,350,396) in place of the RS, SS badges in the front nose of the fender and moved the SS behind the front wheel middle fender area. The 68' SS/RS only had SS enblems. Grill, fenders, and gas cap. The holes for the engine displacement emblems are all the same. If your fenders are new they will not have the holes (at least Goodmark dident), you will have to tap and drill. Make sure the holes are in the correct space. I have seen countless times where people place there emblems in the WRONG place. It makes me sick:
Example of wrong placement:
Here's th correct placement and a damn good looking 68:
I think if you were to do the Bumble Bee stripe on your 68' and only want the SS badge, NOTHING else, and put the 68' SS emblem(which is contoured for that spot) on the Correct place( behind the front wheel) it might look strange I'm not sure.
If you use the 67 SS emblems which are made for the contour of that spot up front in the Bumble bee stripe it would look sweet since you do not want any other emblems BUT.... thats if you don't mind people telling you that thats not correct for 68'......... or they could say "why dident I think of that"! up to you. I think it all matters on what style your going for, stock or custom. Thats my thoughts.
Oh yeah if you do end up putting the SS or RS emblems up front where the engine displacement emblems go.. the holes will be diffrent.
