I just decided to go with the Dynatrac ones for a coouple of reasons:
1. I dont like to trim the bolts, because if I ever need to take the U-Bolts off again, they would be a PITA to put back on with the shorter thread, and since you never know what's gonna happen in the middle of a trail, I rather go safe
2. Skid plates dont really fix my issue; sure, the U bolts would not drag in the mud, but the skid would, which kind of defeats the purpose.
3. I decided not to try and fab one because these ones i know will work right; especially considering the D30's axle disconnect housing, I prefer to go with something that's already tried and true...
Yes, it was expensive for something simple, but keep in mind I make 600 mile road trips with this Jeep, so for $400 bucks or so, I am not just buying U-bolt flip kits, but also piece of mind.
