More '70 L78 Nova questions...

[JHS]

First question: My L78 came with a am/fm/8 track radio. The kick panels had cut-outs for speakers, the dash has one and the rear deck has holes for two. Are all 5 speakers used? What ohm? Does the radio only play in the dash and the 8 track in the kick panels and rear deck, like my '69 Impala?

Question 2: Does this car use a EEC gas tank or non-EEC? Off the cuff I would guess EEC as it has all the smog and TCS stuff???

With ya'lls ( GA term) help I may eventually get this project finished and quit bugging everyone!!
