I'm sure you could probably jam it in there, but it would look like poo.

Does it have a mounting foot? IMHO, the best place for an aftermarket tach is screwed to the top of the dash, right next to the A-pillar. If the dash pad is nice, then mount it to the A-pillar itself (down low, close to the dash).

x2. That's where I had mine mounted (you know, back when my truck wasn't in 10 million pieces?).

IMHO, it would be much cleaner looking than a big hole hacked into a cluster to fit a tach that's not even shaped right to mount in-dash.

If you want it to look decent, just use a stainless button head screw or something and also do a nice tidy job running the wires. It also helps to pick a gauge that resembles the stock gauges and also doesn't have a mounting pedestal that's too tall.

Not a good pic, but here's one of mine:

The steering wheel blocks it, but there's a trans temp gauge mounted down in the lower left opening. It's a small gauge (2 1/8 ?) and even it required a fair amount of cutting the get it to fit properly.

It DOES look like a hack job, even in an old mud truck, not quite as bad though if you replace all the others too but what a pain in the ass messing with the instrument cluster becomes. Which is why I'm going back to stock, and just going to strap the tach onto the column and say fuckit.

LOL exactly, but buyer beware if you find a used one on ebay, they usually dont work. It will be worth the money to avoid the headache of having a broken one fixed, re-calibrated for 7k RPM, and the face re-painted (since most of these OEM tachs are 5k or 6k RPM).

Mine works flawlessly, and I had fuel gauge issues that got fixed at the same time because it comes with a new fuel gauge.

Are the ones on that website brand new or refurbished or something? And just curious what would the redline be for my stock 305?

100% brand new aftermarket.

Redline on a stock 305 is 5K.
