Used nice C2 Auto Meter boost gauge, 30 in.HG to 45 psi. 2 1/16 inch.  Came from a buddy and he didn't end up keeping this in his project (think he swapped to a different engine setup on this car and didn't need this anymore).  He's got me listing some of his stuff for him, I pulled a couple things out of the boxes of his stuff in the garage today to list, so here we are.  I don't THINK this is available in the C2 line currently from what I'm finding, but could be wrong.  Shipping will be $6.00 to the US.
