Part # help

I'm going to be installing a 4th gen rear into my car this weekend and there are 2 parts I need but don't know where to find part numbers for them so I can get them ordered. Can anyone help me with these?

1) 1992 1st design ebrake cables
2) 1LE brake port valve for 1990 firebird

From Daniel Burke's page:

http://www.ws6transam.org/1LEbrake.html

"1LE Combo Valve (proportioning valve)
14089496 1989 1st design: M1.0 tube nut threads (For 1982 - early 1989 applications)
10136840 1989 2nd design: M1.5 tube nut threads (Late 1989)
10136840 1990-'92: M1.5 tube nut threads.
Measure your existing brake line tube nut threads before ordering. The Master cylinder tubes have one that is M1.5 and one that is M1.0 so don't worry about them. Worry about your existing brake lines to the calipers and rear axle. "

As far as the e-brake cables, I don't have a P/N for you here at work but I have it at home.
