Looks nice but had to do some modifications

On my silverado there were 2 brackets bolted to the factory rear differential cover. The g2 cover apparently doesn't not a count for that. I was unable to bolt the brackets to the cover. I had to do some grinding of the cover as well as a couple longer bolts. I like the looks of the cover but disappointed that I had to modify it because they didn't seem to figure in the break line brackets that bolt on to the cover on some of these trucks.

Overall very good, easy install, and look great. The only confusion was how much oil to add as the fill plug is higher than the stock cover. This cover seemed to let me add an extra quart while still having a similar oil level as factory. Not that it was a bad thing, just made it confusing whether I added not enough or too much.
