Hornbrod; its an off road only trailer queen- I'm running 33" right now, and may go to 35's when I've got a bit less body panels left ;) I figure do it once and do it right... As for a good gear guy inside of 50 miles, the one guy that was actually willing to touch them quoted me $500 per axle plus parts!! Sounds like he really doesn't want to do it... Plan B is the 3.73 front; my 8.8 is already 3.73, and to be honest, the 3.55s that were under the truck really never gave me any problems... I'm really only regearing to get two matching axles... Somehow, somewhere... And I figure if I'm gonna do it, I might as well do it once and Max out the Dana 30. (Everything else is stock, if it matters.)
