I've already got taps for.... reasons... (I used the bolt trick when doing my coilovers and spread the ears on the front knuckle too far and royally screwed up those threads), so I just need to pick up the right size drill bit.I have had to drill and tap mine as well. My ACE Hardware had both drill and tap.
NAPA is where I got everything else. O'Reilly only had vac caps in a kit and I just wanted a single cap. for the picture I have a 5 pack but that is because I have been doing cars in my local club left and right.
