The way this fits, there is plenty of slack for placement. Depending on which coil nut you attach it to, the length you cut your bracket, mounting hole placement and size, where you may choose to bend the bracket and even the size of your gauge. No two installations could possibly have specifically the same cover hole dimensions, unless performed by the same person at the same time.......waaaaaaaay too many variables..
Before I cut the hole in my original Red
cover, I first used a sacrifical "used" gray one (picked up from Corvette Recycling
), and cut a larger than necessary 2.5" hole so that the gauge would fit through. Then took specific centerline measurements for the gauge placement and also bent the bracket so the gauge face matches the pitch of the cover. Then cut one, 1.75" hole in my Red
cover exactly where I wanted it
Finding a used, absolutely filthy, LS Corvette "left" coil cover is rather easy, also cheaper than screwing up a good one. (Absolutely amazing.....
....am I the only one that keeps mine clean?)
The tolerance could vary as much as 2" in any direction comparing two different installations.
....Just loosening the bracket nut will allow the gauge to move 1/2". Just make sure you drill the final hole larger than the gauge diameter.........in order to install or remove the cover, there needs to be a little wiggle room
Also, watch that you DO NOT over torque
the 180 degree swivel AN fittings..............or once under pressure, you will snap the aluminum, swivel 180 degree bend and immediately
pump out 5 quarts of oil all over the top of the engine and down your stamped and tinted concrete driveway before you discover it and get the engine shutdown. Immediately, and I mean immediately. Did I say immediately, I meant it too. NO
, do not ask me how I know about this.
NOT the same bracket, mounting nut AJ used....or, the same gauge.
Did I stress a tight enough fit.......
Sacrificial Gray with 2.5" hole.......Red
with 1.75" hole after bending bracket and locating gauge. Your location will not
be the same. Close, maybe within 2", but not the same.
you do not retorque
the swivel AN fitting at 10:00pm the night before you have a 5:00am departure......
....unless you have a spare.
I now have two...
