Progress has been VERY slow on this due to a back injury but with my wife's help I've been able to get small things done a little at a time.

Couldn't get ZF to shift into a couple of gears, luckily it turned out to just be a stuck shifter detent pin!



Front frame rails cleaned of engine mounts and shock towers. I will remove the rest as I make sure they can't be used.

The BEAST, an 11.5 AAM GM axle, overkill to say the least but I couldn't find any other 8 lug axles with the right gearing and discs.

bolted a few accessories up to the engine in anticipation of a trial fitting to the Jeep after I get the 11.5 under the rear to see where everything is going to line up. ZF S5-42 and NP205 (yeah I haven't torn down the 205 yet for a rebuild that's why its grimy).

sorry to hear about your back slowing things down...

What did the 4BT come out of? What are you going to do about vibration (if anything)?

Cool build

My 4Bt came from a late model Freightliner MT35. As far as the vibration I'm using engine mounts on a 45 degree angle, a 6BT damper, and will bump the idle up a bit when its all assembled.

I'm glad you didn't say, "what vibration?" Now you get to keep your teeth.

I look forward to seeign more pics as this progresses.

Thanks, hoping we can roll the rear axle under it in the next couple of days and see just how bad 35s, sua, and no lift other than shackles is gonna be! My plans are for a LCoG as its going to be my DD and I'd like to still fit it in the garage so I can tinker on it during our daily afternoon showers in S. FL. during the summer.

Went to the JY last week and bought these for $80! Front capt. chairs from a Ford Windstar. I tried a set of the Cavalier seats and they were way uncomfortable for my 6'+ body! These are very supportive and they are like new, also check out the under seat storage drawer that was on the pass. seat! The little trays will unlock and lift out to make a large storage space. Sure hope I can use these bases!

Please explain the transmission and transfer case combo. What did they come out of and are you using any adapters? Whats the plan for the front axle?

Looks great!

From one 6-footer to another....i think you are going to have a problem using those seats and still having room. The way the floor is molded you will have to make a bracket to mount those seats and then you will be sitting real high. I often wondered why I read on JF about so many people using some type of seat riser to elevate the seat. I almost wish mine was shorter.

Any B series Cummins requires an adapter. I am using a Ford adapter from a bread van that was in the cummins repower program(see post 4 above). The transmission is a '90 Ford F250 4x4 that had a SB Ford V8. they have a tailhousing that is all ready for most any Ford TC. I had to cut a notch to clear the shift rail on the NP205. The NP205 is just a standard Ford married TC.
The front axle is going to be a little different than most here run. I have both a Dana 44HD and a 1/2 ton Dana 44 both are Ford and have 1/2" thick tubes. I'm going to swap the knuckles around and use the F150 housing with 8 lug outers and the big brakes so I can run the radius arm suspension. That's the plan anyway, I figured it would be easier to keep the Jeep lower by going this route as opposed to keeping it leafs and doing a shackle reversal SUA arrangement and keeping the spring ends out of harm's way while still having a great approach angle.
Time will tell as far as the seats go. I still have some crappy ones the P.O. put in that I'm leaving in until I'm through messing around with the mock-ups so I don't mess up the nice new ones! I'm sure some people are lifting their seats to gain better field of vision while offroading.
All plans subject to change at a moments notice.
