Hey D-Mike, I am not familiar with the charcoal canister to which you refer. Perchance you could send a diagram of the setup, a photo, or a link to a later model Datsun that has that system.
Most of the 510 restos here and images found on the net show the engine compartment stripped of almost everything that was once attached to the fenders and all the holes filled and painted for the "clean" look. I am not looking to do that, but would like the simplest solution to all the extra stuff I have. Thanks.
Are these for your 79 Datsun 720?
I have a set of them aftermarket Bumperettes, they are not the best quality, but I would use them if I needed a set, you will have to make a set of brackets to mount them.
Also shipping is unknown, so you might be able to have them shipped to you directly from overseas.
I can take photos of them if your interested.
