Thanks, I may look for the original bolts although I got the one's you supplied to work after grinding a bit of a taper on the end. Indeed I am Karl from NH - you keep immaculate records :D
What's funny is I was actually hoping these were a little short, for hood clearance issues, so that worked out good. I still have 1/4" clearance even using a 1/2" spacer between the elbow and intake. This allows me to use a N2O plate kit if I desire. After thinking about what you said above, I think it would be more elegant to add big washers to shim the mount internally vs. what I did, which was indeed adding PVC "plate" pieces that I cut to size and drilled/counter-bored to clear the bolt head and washer. The difficulty was having the u-bracket too high to get the bolt through, so I had to machine the pieces thinner on my endmill (they started at about 1/4".) I was using a cherry picker to lift the engine up/down, so that wasn't an issue, it was just being stubborn whereas if I didn't shim both sides simultaneously, the engine would tend to slide to the passenger side.
Anyway, the engine is down, and I finally was able to retire the cherry picker for now. I'm pretty excited about the amount of clearance I have, though the oil pan is still just barely touching the rack, thus I'm now thinking (since I have the most shim possible under the mounts) that shimming with the large washers may be the best "final solution". If I remove the shims, I'll need about 0.2" - 0.25" added in washers.
