Combo Valve fitting sizes??

[booyah11]

Went four wheel disc and haven't had luck with the couple combo valves I've bought so want to simplify.

Would love to just tee the front and add a basic prop valve for the rear, but getting conflicting information on the what the fitting sizes are at the combo valve.

These are the most common dimensions I've found but would like to be certain:
Front of Master: 1/4" line with 1/2 - 20 thread pitch
Rear of Master: 3/16" line with 7/16 - 24 thread pitch
Lines to RF and LF: 3/16" line with 3/8 -16 thread pitch
Line to Rear: 1/4" line 9/16 - 18 thread pitch

Thanks.
