Yeah, all my Danelectros have wood saddles. Intonation is just fine.
My Jerry Jones came (new) with a Fender-ish bridge.
I got a bridge plate like yours, without the saddles, and I had a slot cut in it for the screw to mount a wood saddle. The project it's for isn't done yet, so I'm calculating whether if I can figure out saddles like the bridge was meant to have.
So here are the finished saddles mounted on my probably one off prototype bridge plate I bought. Still need to find the proper hex bolts and small springs but it works just my other one. The plate is cool as it has the same screw pattern as the Jerry/Dano one where as the latter, final version moves the back screw up about 3/16”.
