and was wondering if anyone can give me some info. Just cleaned out the garage and found a few Mach 1 instrument clusters and wanted some info (what years it from, round about figure on what it might be worth) I can email the pics and any help would be appreciated.

Might give you a hand with determining the year/app for your part

As far as value--having watched a milliion Mach gauge clusters trying to buy one--It will bring all the money its worth and more on ebuy
