The seller is claiming this is/was an original LS5 car due to the CRV rear, but who knows without docs. Interesting to see an Arlington built '70 with no paint code (rather than the dash-dash)...I know that was relatively common in Baltimore in 1969, but haven't seen it on other model years or assembly plants.
Cool/nice car regardless....
