That looks great! I noticed you've got one of the aluminum adapters for the stock breather. LCwizard isn't making any more last I contacted him. Do you have another source for them or is just old stock?
This is a top-secret steel prototype for fitting purposes. @JTU is going to remake it in aluminum once it is fully fitted.
Holla at him. The 60’s will probably need a different height & opening size, but those are easy to change.
