I don't know if this is the right spot to put this, so please move if not.

I'm looking to put 3 gauges in a gauge pod on my front pillar, a volt meter, exhaust temp gauge, and a air/fuel mix gauge. My question is this, how hard is the install on the temp and air fuel gauge?

 

here you go some info on putting in after market gauges putting a EGT gauge is just a matter of drilling the exhaust after the headers befor the cat and the A/F gauge you just have to tap the O2 befor the cat or if you putting in a wide band drilling the exhaust befor the cat and welding the bung to mount the wide band O2
