old school blitz boost gauge

[meteorite_flo]

i have this old school blitz gauge i bought a while back on ebay. got it for 50 bucks. it has some scratches on the rim, but you can polish it out. doesn't come with the vacuum hose(you can get that at kragen or something). and doesn't come with the wiring to power it. but if you have soldering skills then it shouldn't be a biggy. 40shipped. and it's yours
