58 chevy disc conversion???

ok guys i know im new here but i need some help. i ordered a "compleate disc conv". for my 58 biscayne for a fella on ebay. Everything showed up and looks to be pretty compleate except theres a note saying vacume line/fitting not included, also it was missing the instructions. So my question is can i run a vac line off the holley carb to the master cylinder/booster?
Also if anyone has a link to a generic disc install I'd sure like to have a little guidance before i tear the front end apart.

 

Do a search here on "scarebird" if that's the ebay'r you bought from, there have been other issues, he does work to resolve them

 

if in fact you do have a scarebird they are very helpful we used on our buick

 

it wasnt scarebird i got em from tomsclassics. i did email him but havnt heard back yet, they maybe closed on the weekends. But id still like input from you hamb'ers
