1970 L78 Nova question...

[mbxlesney]

I would think if your car was a Canadian sold car you would be able to find out if you car was equipped with the RPO NA9 emissions option. I have seen 1 documented Canadian Nova that did have this option. Camaro Specialties in East Aurora NY was selling GM/AC NOS 3/8" sending units selling for around $160 for your application and I would try them to see if they still have any left. My 1970 L78 was sold new in CA. and was a real pleasure to find missing pieces to return to its former glory. For a $36+/- option there was a lot of pieces to this puzzle. Thank God for 1971-72 Novas. Keep your fingers crossed that your car did not come with this option. The Tamraz sold Canadian built tanks are good also. Hope this helps.
