I drive mine everyday and nothings broke. I have a scrambler so I have a longer driveshaft and I kept the tcase the same height and distance as it was stock. I am probably close to three thousand miles so far.

I want to do this very badly. Question, you mentioned buying a " bread truck" earlier in the build. Can you give me a brief background on that, I'm a newb with little experience when it comes to rebuilds. The thing is defintely bada**! my buddy at work is all about putting a cummins in his now too.

You buy a bread truck so that you can have a donor that has the 4bt in it already, and possibly a transmission to use as well. It is good to keep around until your swap is complete because it may have little odd parts here and there that may be hard to find. It eliminates some of the foot work of having to track down all the parts, and they're usually aluminum bodies so when you're done with it you can scrap the body and make some of your money back from buying it and doing the swap!

When I bought mine I got it running and drove it back and forth to work for a month so I could make sure the engine was going to be good and have no leaks.

Will you put some turn signals back in your grill?
If not I thought it would look cool with some rigid D2 led lights mounted in the grill.
