Hello,

I have a tachometer with part # 67403580 and thought it came out of my 71' Firebird, but when I try to reference it, it has no similairities with the original appearence or part #. I have tried different seach engines on the web and I'm not having any luck. Does anyone have a site or reference guide to determine when and what this tach came out of? I think the previous owner may have put this in from something else. The part # is in the lower left in about the 7 o'clock position in the tach. It is a 8k RPM which 1-7 is on the top in the 8 is by itself below the white and orange curve. Any help would be great. Thanks a bunch. Vince
