I watched the videos over on the other Page.
Very impressive to see where you guys take your jeeps.

I forget what all you have in your rig.
What kinda differentials ?
Are you running  T90C 3.339 @ 4.07 x 5.375 in X98 ?

Currently I have Lock Rights in the front and rear 5.38 geared differentials. It is a T90C with RockEater gears in the model 18 transfer case.

Another update. I really didn't like the idea of running 10 spline axles while rock crawling. They just don't seem strong enough. Finally got around to to upgrading to 35 spline shafts. Quite a difference....





I also went with 53" WMS to match the front Dana 30 "narrow track" axle and used a high pinion center section to get the driveshaft up further out of harms way.

[oldtime]

35 spline you say. WOW !  What’s the diameter ? So will the high pinion clear everything when fully stuffed ?

[Bob W]

The 35 spline axle shafts have 1.5" diameter. The high pinion fits just fine in the stock location.

I've been thinking about how low the distributor is on the F-134 engine in relation water splashing due to stream crossings. I decided to make the distributor a bit more splash proof. I picked up a used IAD 4008 (thanks 3-48s), replaced the bushings, installed a Pertronix Ignitor II, resistor plug wires, M-38 style distributor venting and a rubber seal around the distributor cap to body seam. I selected the IAD 4008 because it has the largest spacing between the plug wires of the common Willys distributors. The Pertronix Ignitor II has current limiting, unlike the regular Ignitor, so there is less chance of damage if the key is inadvertently left on. Resistor plug wires are required with the Pertronix units and this also significantly decreased the noise on my CB radio. An inner tube provides the seal between the cap and distributor body. Haven't been near any water yet so I don't know if it actually helps.

The inner tube idea is great!  Is that some type water repellant residue under the wire boots?

[Bob W]

Is that some type water repellant residue under the wire boots?

Yes, it is ignition dielectric grease.

So long as the oil fill tube is sealed I have no serious 134 engine problems until the water hits the fan.
Once the spinning fan hits water level it drenches everything including the oil bath filter.
That’s been my experience every time the creek is too deep and yes it typically kills my ignition system.

It has been quite a while since I have update this thread!! X98 has seen a few changes. I replaced the Rockeater 4:1 model 18 transfer case gears with jpet 5:1 transfer case gears. See the thread over on The CJ-2A Forum for more information about the gears.

Probably the most difficult trail X98 has done to date was Carnage Canyon in Colorado.

Since then I added power steering and a better approach angle. Here is a look at X98 as it stands today.

That X98 copy is too cool to be treated like that.  lol.  What a ride!!!
 
I too love the X98 look. So much so I "personalized/modified" my DJ3A that I call "My Concept Roadster" trying to 'justify the mods' on a rare model itself.  It is still a L-Head.  The front grill shape, and hood to conform are its most obvious mods.  Pic attached.   Unfortunately, project has hibernated since 2016 due to medical issues.  Maybe someday I'll get to finish it???
