Anyways, more mods. Ever since I put the 203 in the rig I had issues with the 7/16-14 (coarse thread) bolts that thread into the aluminum adapter plate coming loose. Attempts to retorque resulted in a few stripped threads, so I just jammed some M12’s in there as a stopgap until I could fix it right.
Obviously being the splitcase there are a few bolts that can’t be accessed without case disassembly.
So, I installed Time-serts in the adapter.
Fresh steel threads will let me torque the bolts to higher values and make threadlocker compound more effective. I may also safety wire some for triple fix.
(Many people don’t understand that threadlockers are anerobic and won’t really be super effective in stripped threads because of tiny air pockets)
I also noticed that I was missing the M12 dowels, that located the transfer front half on the adapter. One of the holes for which isn’t even drilled, thanks Advance Adapters!
This is probably not helping the bolt looseneing either since the transfer case was probably shifting around on the adapter

I circled the missing dowel locations, need to make some dowels and get them installed unless someone has the part number for the Toyota dowels in the back of the H55f. I didn’t have any luck. I could buy them on McMaster but I’ll probably just make them so I have them today.
