I want to add a tach to the stock gas location, but I am on a tight budget. I love the looks of Solo-Wookies dash, but I do not have the budget for all new gauges, and I think a new tach w/ the rest of the gauges remaining original would look a little trashy. I have been told that stock Camaro gauges will work in the 73-91 dash. I need to know what year to look for and if anyone has done this I would love to see pics and know how involved the mods of doing this are. Thanks.
