I think you definately should restore the green one. The pine needles are scary because they like to hold moisture under them and rot the pizz out of metal, but it looks pretty good otherwise. The stock 7.5:1 compression motor is pretty forgiving and refreshing the brake/fuel system can be done without breaking the bank. Mild or wild it is only limited to your desire and pocketbook.

As for the yellow one - that looks really bad. So bad that you really should send it to me here in MI lol

I'd say both are restoreable if you can pick them up cheaply enough. Go for it!

And welcome to the madness.
