I missed how you affixed the Aluminum grill guards to your steel hood, but I did want to let you know to look out for Galvanac corrosion. http://en.wikipedia.org/wiki/Galvanic_corrosion.

^ I understand what you mean but you don't have to put zink blocks in there. The aluminum will corrode before the Steel as a sacrifice.
Text book Quote (ISBN 0-13-243037-1)pp8:
"Galvanic corrosion, also called sacraficial corrosion, occours when two dissimilar metals come in contact in the presence of an electrolite. An electrolite is a non-metallic conductor of electricity. For example, if a bare aluminum panel comes in contact with a bare steel fastener, the aluminum will corrode to protect the steel fastener. Coated fasteners, washers, or gasketscan be placed in between the dissimilar metals to prevent Galvanic corrosion."

depending on the price of a zinc block all my vehicles may be getting sacrificial anodes very soon. I say that for even $50 thats worth the savings of not having to fix rusting spring perches like I have and/or various other things. >.<
I'm waiting for a leaf spring to punch a hole through the floor where the unibody is rusting above both the front perches. Need to cut them *****es out and weld in a nice fat 3/16ths steel plate that runs across the whole floor.

Ive been following this thread for a while, and I just got all the materials.
Im going to try installing it tomorrow if I dont have anything else planned, should look pretty sweet!
Just hope mine turns out as nice as yours..seeing as how I'm a perfectionist, shouldnt be too bad!
Im using your measurment guide because I like the setup. Ill be using a primer/finish flat black for the mesh, and it'll be on a white hood instead of black, so my cutting and finishwork has to be a bit more precise, defects will show on mine!
Ill post when it's finished!

Those look nice! If I didn't think I was going to mess up my hood (because i'm more of a mechanic and less of a painter/body repair man) I'd do it. Maybe I should go take a hood of a rear end damage XJ at the salvage yard? I was thinking of going for a cowl induction look.

yeah, but part of the fun of these rigs is the customization.
I saw some of the ones at west marine, not bad.
But for the same cost you can make your own, and its all about the 'fabrication' and not just ease of install. Im looking forward to making my own when i wake up today (its sunday now!). Time for bed
