Hey Chevymad, thanks again for coming out last weekend, hope you had fun out at Tillamook. As far as differential skids, I don't use them, but I have thought about them from time to time. I have aftermarket differential covers, that's about it. Right now I am not big on skids because of the potential loss of ground clearance with some of the "bolt-on" skids out there. I may change my mind someday, but here are a few options if you are looking.
The top-left one is the AEV/Nth Degree Dana 44 slider which bolts on. It even protects the pinion and lower CV joint. I think you can mount them on the front too if you run a front Dana 44. This is the one I thought about getting at one point.
The bottom one is the slider made by "Rock-It". It has a similar concept, but again you can see it hangs lower and you lose a little bit of ground clearance with it. Probably even more than the AEV one.
The one on the lower-right is made by Currie and it's on their Dana 60. This is not an aftermarket option, but rather a "built-in" option for their aftermarket axle housings. I just include it as an idea if you are the fabricating type. I think they only do this for their Dana 60's so I don't think you can order a replacement plate from Currie, and just "modify" it to fit unless you have a HP Dana 60 too. This design seems ideal since there is no real loss of ground clearance.
I am sure some people may agree or disagree with my comments, and there may be other skids out there but these are the only ones I know of. Hope it helps and hope to see you out on the trails again sometime soon!
see ya later-
