Guys I have access to NOS 2GC for my skylark. Should i expect this to work straight out of the box, or would i be better off with a remanufacured car. Also is there a big difference in 2GC before 1970 and after? will a 1972 2GC allow me to have full ajustments of the mixtures or do to smog control would i be better off with older version of the 2gc thanks, also i am new to posting on the forum
