I used just gasket maker on mine. Thats what it suggested I do believe.
And as for everything else mentioned. Those of you who are thinking about them... GET THEM.. they make a great difference for the money, I have two 10's bridged on a 750 amp at full power... and I notice no dimming, no loss of A/C or anything!
I want to get one pretty soon. But I don't have any air tool for that Alternator bolt that everyone's talking about. Will my 3" breaker bar do the trick?
as for breaking the alt pulley. i didn't have air tools. I hooked up a breaker bar and put about a 6 ft piece of PVC pipe on it and yanked the crap out of it.
no SOTP help from my MAC ud pullies... I didn't do the install myself, paid 50 bucks to get it done. In fact, if anyone wants to trade the stock alternator/waterpump/crank pullies from 96 for a set of MAC UD then i'd be willing to do it. Just got a vortech and those UD's sorta defete the objective.
