ok first off, I am going to putting all aftermarket guages in my dash.

I would love to put in a 5" tach and speedo in but i am worried about whether or not they will fit where i want them, the fatory guages are somewhere around 4.5".

i was wondering if anyone uses 3 3/8" guages and whether you think that they will be big enough for those two guages. Are they easy to read?

 

factory gauges are 4" for a firebird if you measure inside where the gauge actually is. I'd be worried about depth also.

 

i am going to be taking the whole exisiting cluster out so i dont think that depth will be a problem.

i did find out that i will be able to get the 5" guages to fit.

 

oh sweet! Post pics when you get it finished.
