OKAY! NOW YOUR IN TROUBLE......VIN 5TH DIGIT FOR 1968 PLYMOUTH............ C = SPECIAL ORDER 6 CYLINDER.Yes code for engine is a C
I'd take it for a spin. Does it drive and stop?
Note any overheating, leaks, smoking, or engine noises.
If it runs and drives and doesn't have multiple issues roadworthy wise I'd offer 14 cash and then move on.
I'm not a body man....
Commando was the term used for early B-Bodys I don't think 68's.Thanks for the info on that he said it was 383 commando car
