What’s the wheelbase on the Buick? I’ve been working on a trailer design that will accommodate my Jeep and anything up to a 4door wrangler ish wheelbase. Taking a page out of @Hickey ’s book it will be a single axle with G rated tires. Torsion axle and low. Could be pretty easily extended if needed. Targeting sub 1k lbs for the frame only. I need to get back on this thing and finish the design and make sure dexter can make the axles the way I need.

116" wheelbase on a 68-72 A-body. 100" on my trail Jeep (at least as it sits). I'd be up for building a twin trailer to your concept. I'd want to analyze weight distribution between the Buick and the Jeep to optimize towing with a single axle. I would likely just replace the tires every 5-6 years as much as I trust trailer tires.

The way this is setup now, it has a bit more than 15% tongue weight with my jeep on it. i can't remember the numbers exactly. much less than what my 3/4 ton truck is rated for.

What’s the group build price on these bad boys

What’s the group build price on these bad boys

Not sure yet. Need to finalize a few details and start getting quotes. Plan was going to be to have it laser cut then assemble a jigsaw puzzle. I’m sure doing more than just the one I was planning on will make them cheaper…

That's a lot of registration tags

Fixing some more of the carnage from Labor Day 2022. Thought I had a bad output seal. Taking all the drive lines, crossmembers and such out and found the source of my leak was not necessarily the output shaft of the trans.

Novak will get a call Monday. Hoping not to pay $600 for an adapter and bonus spud shaft

You think he can weld the cast alum?

 

[Hickey]

You think he can weld the cast alum?

Yep.

 

[SoopaHick]

You think he can weld the cast alum?

Yes I can indeed weld this... Though my tig welder was giving me fits the other night so I'd have to address that first.

The area around the Bolt and Nut may be a little tricky but it's definitely doable.

That adapter you have vracked is just a stock cast aluminum one as I'm sure you know. We (she) broke one on Stacie's V8 YJ and it was very cheap to just find another one. The application I found was a '90s Chevy 1500 with a 700R4 to NP 241.

(The uncheap part was that the tail cone on her 700R4 was also cracked)

 

[mbryson]

I just got a call from Novak. They would like the destroyed version sent back and we made a decent deal on a new unit (hopefully exactly the same but mine is 20 years old so it may have some variance?) Should have an adapter by Thursday or so?

Every stock adapter I've looked at have integrated "feet". I'd rather not redo my crossmember setup if I can avoid it. This should move under it's own power by late Thursday night if I don't have other issues?

I don't "see" any issues with the trans case but we'll see how it goes. I was nervous about using the stock unit you outline above as everything I've seen has the "feet" cast into the adapter.

 

[mbryson]

This is what I received. About 3/4" shorter than my current adapter. That means I'd have to lengthen/shorten drive lines. The adapter also has horizontal bolts to mount the adapter rather than the vertical bolts of the old unit.

For a transfer case I'm not fond of and a Jeep that I am not sure of it's purpose at this point, I don't see a reason to make this adapter work without doing other changes. Lots of thoughts going through my head.

• Part the Jeep out-not really interested in doing that
• Chev 241 or 208 (I don't use front or rear dig regularly)
• Atlas II like I should have done years ago (how often will I use this Jeep? Do I make it "street able" and dump the JT?)
• Find the GM 241/208 adapter and redo the crossmembers mount keeping the Dana 300

I chose the last option for now. GM adapter on its way.

While the other adapter is on the way I contacted Novak for a return. Novak is trying to find me an older style adapter. There's one on E-bay but I'm pretty confident it's an Advanced Adapters unit, not the Novak it claims to be. If I can get the Novak from Novak themselves, I'd appreciate just doing that.

Jeep has been down for a year, a few more weeks won't kill me?

 

[Hickey]

I think you need to go hard on a refresh for this rig. Spend some real money to make the changes that have always bugged you. Just like Greg, you need a light wheeler like the JT and a hardcore rig to keep the JT happy as a daily. Fix the adapter for now, but plan for a serious refresh.

This is the old RME dude formula for happiness.

It will be getting some refresh and updates for sure

That's screaming deal! I paid $40 shipped for the one I ordered.

 

[ebryson]

It's a little broken....

 

[mbryson]

Mating the two adapters to have the right bolt pattern for the D300. 4 holes line up. Clocking is off a wee bit....

Probably help my drive line angles a bit? I'll have to rework my flat skid as the D300 "pan" has contact marks, I assume from the skid plate?

 

[mbryson]

I kind of need an output seal?



I'll have to check out the Advanced Adapters ADV 50-6304 and see if they'll just sell me the alum?

Advance was able/willing to snip parts from the kit for what I needed.
