Bob, did not find any D/S single 350 valve covers in the parts stash. I did come up with two pairs or sets. One set uses the twist lock oil cap and the other uses the rubber grommet or cap. Believe the twist lock was original for 69-70 years and the rubber grommet or cap was used in 71-72. Maybe some one else with more info can chime in on that?

Either set is available altho not wanting to break them up as sets. Both sets need cleaned and repainted. No rust or scale but both are dirty. $45 a set if interested in either set plus shipping. Understand if you don't want to buy a set if just needing one but as mentioned don't want to break up a set. LMK if you have and interest, best I can do with any valve covers at the moment.
