Sorry guys, I too want to know about this one too...
I am confused... Tod said : "The VIN Number is the only way to know for sure"
rlmotorsports says: "tod74 is right you can't tell by the VIN tag on a 70 Chevelle"
I get the part about the dash cluster (round guage vs sweeping spedo, etc..) but how would a VIN on a 70 -vs- 67, 68,69 etc... having a 138 be an SS differ from a 1970SS?? Is the 70' VIN using a different code than the rest? I am curious myself as this is one of my favorite years of Chevelles. Scooter
