    I was thinking of a 243 or hd246? Or rather a round about way to get a transfer case and 4L80e upgrade. I see those transfer cases all the time. But not the 208 and 241c that fit a 4l80e.

    The one I have in the Blazer is a Dodge NP241DHD, they also used the DLD's on the diesels. So if they hold up to the Cummins they should handle about anything.

    I was just going through my pictures and found one of my finished front bumper, also my helper had to have her picture taken. I had to put the section of expanded metal above the bumper to fill in the space below the grill where the intercooler is. Also the hood pins aren't there to keep the engine in, I had to remove the safety latch because it was hitting the top of the intercooler when the hood was closing.

    Since I didn't get a spare tire mount with the Blazer I was going to make a swing away and mount it on my new rear bumper when I make it so I could get my big spare out of the back and have some room to haul something. Then I got another idea to just make a shelf that sits on top of the fenderwells and a couple boards on the rear sides to keep it flat. The middle of the shelf rests on top of the spare, the nice thing it hides everything in the back. I have my 20' 2ga cable that I use for my 12,000 lb. winch that i'll use on the front or rear. In the winter time I carry a 100 lbs of weights mounted on a board so they don't slide around. The boards I also put on the floor right after I got it because it had carpet the was all stained up and under the carpet was a 1" thick hard foam pad that I wanted to keep for sound and insulation.

    I had a Power Trax Lock Right NIB laying around for quite a few years so I decided to install it in the front axle.
