fitting sizes on proportional block

[sackracing]

Does anyone know what size the two fittings for the front and rear lines to master cylinder on top of the proportional block are? I tossed my old steel lines before I could measure them. I'm going with hoses and and fittings from master cylinder to block and need to buy the adaptor fittings.

Thanks

The front line is a 1/2"-20 with 3/16" OD tubing

The rear line is 7/16"-24 with 1/4" OD tubing.

I measured these from a set of lines that were on an '87 GN. Don't see any reason that they would be different then an '86.
