So I took the old MORE tray out yesterday and installed the Genesis kit. Everything went as planned and I'm impressed with the Genesis kit. So a brief summary of how it went. Took the old tray out and hacked off the portion where the fuse block went.The MORE tray used the OEM plastic portion still, the Genesis kit only keeps the small portion that holds the stock airbox. The OEM plastic is ribbed pretty extensivly so it should be fine holding the little air box. On both trays you have to grind down the bolts on the firewall, Genesis does not include little caps, these are just $.25 caps from Lowes, but the MORE kit had them so I reused them. The most noteable thing besides the obvious isolator installed on top is the battery clamp. A bolted down top plate is much better than the straps from the MORE kit. With the MORE kit I was able to slide the batteries aroound in the tray a little. This is probably not a big deal but I didn't like it. The wiring installed from Genesis is top notch, all the clamps fit and the cables were installed with good quality terminals.
A side note, I have the hood popper kit (Teraflex). I had to flip the struts over b/c the fat part of the strut was VERY close to the positive terminal ring thing they include. Once it was flipped I had a inch or so of clearance and since they are all bolted in place I'm not too worried.
I will post some pics of it installed tonight. The pics on my phone looks like crap so I need to take out the camera.
