Yes it's 4 wheel discs . So my brake lines will hook up, correct? No other changes?

If the physical dimensions and mounting holes on your TA prop valve are the same as a G body you should be OK. As I mentioned earlier , the Cadillac Seville valve Is a direct replacement for the G body with no fabrication required.

I had the same issue with no pedal after swapping to Cadillac rear disc brake setup while bleeding the brakes. Had to bleed them 5 or 6 times before I got a hard pedal and brakes that work.

I would also like to add that if you got QP's base disc kit, it is indeed the Seville/Eldo calipers. They are a mf'er to bleed. To aid this: cycle the e-brake a few times in between bleed sessions. The pistons ratchet out as you use the e-brake, thus reducing piston travel to the rotor.

E-brake cables to long ? What are they doing to shorten them up? Got a U shape thing to take slack out of the cable and the first time I used the e-brake it broke.
