View attachment 1715708370 It’s funny that you posted this as I was looking for the 65-66 style for my valve covers. It looks like Layson’s has them and the correct oil fill cap. I live close so I can just pick them up.
This post show both styles of Commando valve covers.
These being the earlier one with the stove pipes for both the breather and the PCV, also notice the fin pieces do not have the hole for the plug wire clip.
The later style have a domed section at the PCV and breather and these have a hole for the plug wire clip.
