I think all calif cars when new have a sticker stating what the emisions out the tail pipe are. so when they are smog checked they can`t be above that.
Your 83 doesnot have any additional emissions equipment. except for the EGR valve.

I think the 84, like the 85 has the different tach pick up on the bell housing. and maybe the computer box thing behind the passenger foot well kick panel. I think JIMMYL had a problem with that a couple months ago and a writeup.

now the 85 has all the wonderful CARB added emissions equipment.
I have had mine 11 1/2 yrs and runs great zoom zoom.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
