Rear Disc - Wilwood PV Needed?

[MtBraun]

I installed a rear disc conversion kit from TSM on my 78 K15.. The fit and install were nice. Anyway, I purchased a Wilwood adjustable PV with the brake kit, and after reading the posts below, I'm confused how this is installed, or if it is even needed? I also found some other internet advice that had the PV plumbed in right after the MC and the stock unit removed, but that install had both front and rear lines "T'd" into the PV.

So my question is, do I need this for the rear disc conversion, and if so, what is the proper installation?

Thank you.

First disclaimer... I don't have my own personal experience with rear disks on Squares...

Everything I have read on a few other great truck sites the guys doing this mod say the stock PV will work just fine.
At least try the system before you go and change out PVs.
