Great looking machine Dave, I actually LOVE That original Color,, kind of a Burnt Orange? it looks like... very cool, I'd love to do up a machine in that color scheme.
Also, glad you got the other one I sent, and yes,,, I'm guilty I planted little "Vending Machine Eggs" inside the other machine and figured they'd hatch while in transit... ta da... !!!
I've restored 2 of them so far and think I have it down so will be glad to help..
First off, you said you got the main door open? good... the lever to release the back side is located right in front of the coin mech, See first photo.. just lift , pull out and up toward you, and that will realease the lock that holds the back on .. once released the back will slide off.
next is to get the taper pins out of the shafts that hold the selector knob and the chrome crank down lever, this will be the trickiest part, and will take some patience, a long tool to push it out and your favorite swear words... but should come out..
once those are removed, a few small screws and the whole mech should slide out.
The front chute, as bubba said, should just slide up and off with a little pressure, or small tap with mallet...
Please ask more questions if you have them and I'll try to help.
I'd love a real large photo of that machine to show that color to my painter... I think I want to do a stoner jr in that color... you can email that to me... largest you can get.
Thanks
John
