Defrost Help!!!

Ok So I have another question. I figured out that there was no vacuum on the system. (The owner before me didn't have it hooked up at all) So my question is, Can I just hook it up to a "T" off of my brake booster? Or since my 4bbl Carb has a port off of it (the one that typically could run to the auto trans) can I put a line off of that or is that going to affect performance in any way?

Use any intake manifold source. The brake booster is 3/8", I would try to find a smaller port. Sometimes there is a vacuum tree with more than one outlet in the intake and it also has the big port for the brake booster, use one of the smaller "legs" of the "octopus", or use one from the base plate of the carb. Or use a tee in one of the smaller diameter lines, as long as it's intake vacuum, not ported vacuum which is for the vacuum advance on the distributor...
