Sounds like a pretty sweet second truck! You should start another build thread for that project.
Hey Mike, I just ordered my slipperential and UCD mount and I already got the Ofna 131mm and the Duratrax 83mm center shafts. I was going to see if you could measure the holes where you mounted the UCD mount onto the center skid plate for me, so I could use the same center shafts?

(Pretty Please!!) Also, do I need to contact Monster Mike about obtaining the right length upper bracket for the UCD mount? As I noticed you had problems with fitting the slipperential into the UCD mount on page 3.
Any help here will get me going a little smoother. Thanks in advance, and I am going to start my build soon and hope to finish over the winter time while work is slow.
