1. First the box dilemma. I designed this with flanges that tuck inside to be spot welded so it would be easier than welding seams with a mig. Works okay but the jaws on our spot welder head butt the opposite edge in a couple places, arrgh. Not terrible but forming this was a bear! Might be a better idea to use small sheet metal screws? or rivets? or just remove the tucked in flanges and seam weld? Opinions?? when I have the flanges tuck in there is a small gap in the corners, do you think this needs to be water tight or just a dust cover?

2. The flippin crappin lights I angled both upper corners at 45* one side to stay inside the edge of the tin the other to clear the light (instead of rounding the corner like the template) but my box and the one I made from the paper template interfere with the odo reset (barely) so I have to make it just a bit wider. So why not enclose the inboard light under the box too? (pic 4)

3. along with Q 2, if I enclose the light will It cause interference with the Tach? I don't have a tach, and does a factory tach even work with an LS?

I keep trying to make these lightbulbs work but seriously think I will have to go with small LED lights to get something I am really happy with because they are just in the way soooo much.

My flanges are too wide and screw holes are too big so nevermind the slight overhang. Will try some more improvements tomorrow.
In the interest if making this easier for anyone to do (you did volunteer didn't you? ) I would say forego the spot and seam welding and go with sheet metal screws referencing factory holes if possible. I would think it only needs to be a dust cover not water tight. I for one would prefer to not even use the trip odo so the reset interference is of no consequence to me. I would suggest covering the offending light bulb if it can be done without interfering with a factory tach.

Keep plugging away man! Many thanks!
