C/20 Master Cylinder Distribution Block ?

I have a old school hydraulic trailer brake controller spliced into the distribution block on my 71 C/20. Can anyone tell me the actual size of the outlets on the block itself. I need to plug the outlet on the block when I remove the controller because it’s starting to leak...thanks

Re: C/20 Master Cylinder Distribution Block ?

Maybe not much help here, but typical SAE brake fitting thread sizes are:

3/8"-24
1/2"-20
9/16"-18

Less common is 7/16"-24.
