Hi Otaku,
Thanks for reaching out to me via PM, asking about my Bally Hay-Ride cabinet dimensions, and directing me to this thread. I replied to your PM, but just so the information is public knowledge, I figured I would include it here as well.
I measured my 1964 Bally "Hay-Ride" cabinet and across the front it is about 22" wide (a little less across the cab, a little more across the lockdown bar) by 13.5" tall. The back of the cabinet measures 18" to the top of the backbox neck and the whole cab is 52" long. Hope this helps!
I'll be following this restore thread closely! Kudos on tackling an ambitious restoration like this. Best of luck, and thank your parents for allowing you to use their washing machine for your wiring harness. Ha-ha! ...or wait. Do they know? (Maybe don't thank them.) *LOL*
