good evening fellows, i just have one question tonight. On my 67 400 4 speed car, what numbers do i check to see if it a real matching numbers car? the previous owner was a very elderly gentleman and he said the drivetrain was all original. i believe it is a real 400 4 speed car as it has the right bumper, grilles, decklid and they are worn enough that they look original. also, it has dual traction ars on the rearend. if you could tell me what #'s to check, where the are located, etc. i would truly appreciate it. thanks
