Had a productive weekend. Got to spend a full Saturday wrenching with
@DieselToyPullr Loaded up a truck bed full of parts from Tim's garage that will go a long way towards getting this thing put together. Now they're clogging up my garage instead of his

Still gotta go dig the axles and spare hard top out of the field they're sitting in. But I'll get to it eventually.
Pulled the tail housing off the transmission and swapped out the factory 21/21 spline sleeve for a new 21/23 spline sleeve from AA. Realized that the input shaft on the front t-case is actually a 21 spline, not a 23 spline like I originally believed. No biggie. I have a spare Marlin Competition 23 spline input laying around somewhere that I'll swap in at some point. Got the transmission and dual cases test fitted, tunnel marked for shifters, and removed for an eventual full reseal. I was a little worried the TG cross member I picked up wasn't going to line up with the factory cross member frame mounts. The guy I got it from wasn't sure if it came from a pickup or 4runner, and wasn't sure what year it was for either. But it happens to line up perfectly and bolts right up! And it was $free.99! I forgot how long these setups are...but it's exactly what I wanted for this build. Looks like I'll be completely losing a center console. But that's okay...I'll still have a glove box.
Decided to go ahead and pull the motor since I had already removed almost everything that needed to come off in order to pull the motor. It was a tiring but rewarding day.
Next step is to drop the gas tank, then pull the truck back out of the shop and get after it with degreaser and the pressure washer. Need to clean up the engine bay, frame, IFS stuff and the entire underside of the truck now that almost everything is out. Once it's completely cleaned up, I'll cut the tunnel and get the carpet and seats installed. Then I can start removing the IFS parts and cutting stuff out for the solid axle swap (way easier to do with the motor out). In the meantime, I'll be able to more fully assess the existing wiring harness and make decisions about the motor. Some parts of the engine wiring harness appear to be a little iffy. Some of the connectors are brittle and/or cracked. And it looks like critters may have gotten to some of the wires. If the harness is largely salvageable with some isolated wires to splice and connectors to replace, I'll stick to the plan of getting a fresh 22RE long block and rock on. If it looks like I need to get a whole new engine harness, I may reconsider my replacement motor selection. More to come later.
