87 YJ Vacuum Routing. HELP!!!!

Hey guys, i've been reading for about 3 hours now trying to figure out this mess of vacuum lines going on in my 87 yj with the 4.2.
I started off with rebuilding the carb, and labeled everything i took off. My only problem now is after reading (and doing) the nutter bypass, i found out my dizzy didn't actually have anything connected to it. and now i'm right confused... i dont have the stock vac routing diagram, i bought a hanes manual, and now i read that i can pull a lot of the hoses out. It's been a long sunday, and i need my jeep for work tomorrow.... any help would be much appreciated. I need to know where my stupid hoses go, and what i can rip off.
Thanks for your time,
Mike

Did you adjust your ignition timing after the nutter?

You need to provide the distributor with a source of manifold vacuum

Let us know if you adjusted the ignition timing, there must be a source of manifold vacuum on the Carter, I can't remember where it is since I got rid of it a long time ago, but I know it's there.

I did indeed advance the timing. there is a capped off vacuum hose running indirectly to the intake manifold... by capped off i mean someone pushed it over the battery holder hahaha. i'll try that.
