On the nitrous plumbing A1A I have some pictures of my setup.. I was just looking for some quick answers to some and fittings I was purchasing.. just more wanted to make sure the metal zinc wasn't going to have an adverse effect fitting to aluminum..
In the end all for naught as when I went to order I fell short of the promo and ended up spending extra $15 on aluminum fittings to get the promo and and got them for just a couple more dollars each in the end.. story of my life I can't win or I did win LOL I'll never know...
