I went through a strap lock search just 2 months ago.
I did not want to drill or fuss with getting every guitar and strap set up. I have had metal clip locks fail.
The most inexpensive and easiest method I found were to use :
D'Addario Dual-Lock Strap Lock
Just finished updating my Casino Coupe. It gets the most play at my house, despite being the least expensive guitar I own. I decided to put some time/money into it - DiMarzio mini humbuckers and Grover locking tuners. I might change the pots. if I can find the right ones - I like slower turning...
Just thought I would share some info. because I had trouble finding anything online. Grover couldn't even give me a definitive answer. Anyway, the Grover Vintage Locking tuners (model 533) fit on my Casino Coupe without any drilling.

I think I have the issue figured out. I took out the neck volume pot. and looked at it's wiring.
I will post pictures - just waiting on a pickup ring.
I appreciate your help.
Hello Folks,
I managed to break off 2 red wires from the neck volume pot.
There are too many red wires and I don't remember where they go.
I tried searching the nets but have not found a wiring diagram for the Casino Coupe.
I also tried soldering them to different points and have gotten some...
