What do you mean the PCV and Gen V are too short?
There's two ways you can do this. I already posted in this thread on how to do it, but I'll repeat.
1: Cap 3/8th nipple on back of Gen V and run a Valve Cover Breather.
(I don't prefer this way as I'd like to make the PCV functional. This lets unmetered air into the engine and could cause your LTFTs to be off).
2: Drill out brass plug on bottom of L67 Throttle Body. Tap the hole and screw in a 3/8th fitting and run a vacuum line from there to the Gen V nipple. This makes the PCV functional.
