[maze951]

hey guys, i bought this 82' about two months ago.
paid $700 runs great. i got the title. registered it and when i went to go smog it
they didnt wnt to do it due to there wasnt a vin on the dash nor on the door jam.

so i took it to chp, and dude told me he didnt find it in his confidential spot.
so i just need some help on where i can find the vin. i need to get the loction so i can just get this thing smogd and on the road.

any help would be entirely appreciated. thanks, Jimmy.
