OK, so I'm still struggling my way through the disc brake conversion. Front brakes are mounted, as is the proper master cylinder. Now I need to deal with the proportioning valve. My plan is this- use a T-fitting for the front brakes (with a line lock between the master cylinder and the T), use an adjustable proportioning valve for the rear brakes. So here's the problem I'm addressing...the adjustable prop valve I'm using has fittings for the smaller brake fittings , the front-to rear brake line is larger diameter and uses larger fittings. How can I make this work without replacing the entire front-to-rear line?
Thanks.

OK, so either this is the stupidest question ever...or I'm breaking new ground here. Either way looks like I'm on my own. Oh well, it ain't rocket science. :)

look for a reducer fitting - I'm sure you can get them at the local parts store.
