i see lots of repop stuff out there , where is the best place to get the bezels/ lenses to clone a 68 dart from a 67 im only looking for the exterior body stuff headlight bezels, tail lens/ bezels marker lights for the sides,etc....is there a one stop shop..

You can't just swap the tail lights as the buckets are different. I won't even get into the interior differences and electrical differences.

I can tell by looking at the underhood wiring whether the car is a 67 or not........ (not bragging, it's just that easy).

Buy a 68
