On the inner fender too?
I have a 34mm case.
I also run the Marks over/under gears, Marks only uses the 34mm shaft and gives a bushing for the 38mm case.
So, anyways, here’s some more tech.
The front output selector shafts are actually the same length, it’s just that the forks are oriented differently and some different machining done at the ends.
The High-Low selector shafts are oriented differently as well.
The high range gear set on the 38 is larger. Haven’t counted teeth yet to verify gear ratios.

Yes! Been a great learning curve.
So my machinist friend Jerry, opened up the input side bore of the 38mm case to clear the adapter’s output bearing retainer snap ring, basically to match the 34mm case. Fits perfectly.

Another great thread for reference. One of the many reasons to love this site! Thank you @Hugh Heifer

Split Case Rebuild
I got a free split transfer case here on mud for a project and looked around but did not see a good thread on the rebuild of a split case so I figured I would do one. The plan is an H55 and a split case in a 40 that I am going ground up on and the truck is to be a camping/lite trail and...forum.ih8mud.com
The undercoating still needs stripped off of the underside of the inner and outer fenders. While I had them out, decided to try to clean the stubborn buildup of dirt that has stained the sides of the inner fenders with vinegar. This seems to be another thing a lot of Cruisers have in common from years of driving around on dirt roads and such. The silicas like to bond themselves to the paint and resist the normal auto store cleaning products.
This was more of a trial for other guys to see, as all this on mine will be painted over anyways.
So yeah, vinegar and and a green scrubby. And elbow grease.

On the inner fender too? I knew you filled the firewall hole, just don’t remember about the inner fender. I guess it would make sense for you to fill it unless there was something else to utilize it for![]()
Stripped the undercoating.

Also, got the tap in earlier this week to thread the hole for t-case front output selector shaft detent. Mud info was spot-on -

High range should be 1:1 for either case, eh?
Can't believe I haven't been in here reading for a month!
July has kept me hopping - can't wait to see what you have been up to!
Nice! So you are giving your Piggy the 38mm shaft?
Is this part of the vacuum to mechanical conversion?
I love that build! Don't forget the little freeze plug that @Hugh Heifer forgot...
Are you getting rid of the blower motor?
I can't wait to see how it all goes back together!
It sounds like getting the doghouse to align is what separates the men from the boys.
I was already living on borrowed time in my project, so luckily I was not tempted to go that extra step...
Good morning TJ
Yes, both cases have a 1:1 high range ratio. Some of the aftermarket gear sets change the high range ratios. I’m looking to sink a 3:1 low-range set that Kurt sells when the budget recovers which still retains a 1:1 high range. There is a 3.3:1 set that reduces the high range by 10%. That seems purpose defeating to me when trying to get the best of both worlds in highway speed/rpm and trail crawl ability. The thinking could actually be that if a guy were to retain the 3:70 diff gears, the 10% high range reduction would give you the feel of 4:10 diffs.![]()
