"Frank The Tank" frog mod ?

Anybody care to share how is the best way to attach the barrel swivel to the frog for the paddle tail attachment. I see the split ring and center pin but the attachment inside the frog is what I'm referring too. The Teckel Sprinker frogs are all back ordered.

Booyah makes a version. Not sure how it compares.

They run wire harness around the hook inside of the frog and then attach the swivel.

Dicks has them on sale for $4.99 each
