Anything tricky here? Any weird issues like an impossible thread match or can't use off the shelf aftermarket gauges for some reason? My gauges are rather crappy so I want to swap in straight mechanical ones for the oil, water temp, and voltage. Any reason I cant pull a sender out of the top of the head and screw in a mechanical sender? Same for the oil on the driver side of the block? Or are there any other unused locations to install the gauges on the block/head?

Thanks to anyone that can save me a little time finding something out the hard way.
