^^ Is that comment directed at me Sir? If so, I accept the appellation. I freely admit to being a tad retentive when it comes to my engine bays. I mean, look at how dirty mine is these days.
The underside of the hood is actually dirty...
OK, OK, more than a tad...
Sheesh...
At any rate, this installation is looking stellar. This is a first, as far as I am aware, for installing the T-Bird Compressor into an XJ. It is also a first to locating it in this fashion. What is going to be nice is that it will all fit under the stock hood.
And, IMO, that has value in and of itself. A little Stealth never hurts.
I would be inclined to give that pinch seam a little "positional persuasion" as that bolt will strike it under torque load. If a button head bolt would fit, that would gain some clearance. Maybe, enough.
One could raise the engine mount on that side with a spacer but, that creates other issues.
