I made a walk around and first start video this week. Hopefully next week I can start some TJ dyno videos.
I added a flattie to the fleet

Don't project toys always get a little out of hand?
So, is it better or worse than you thought, and what's your new plan for it?
Don't project toys always get a little out of hand?
They usually do. It's about what I expected. I knew about most of the body and rust problems. I also knew the transmission was bad. The axles I didn't realize were that bad and needed extra attention. I have the engine out now and I hope it doesn't need much.
Yes T90. I used a needle scaler on the case and bought new parts for the inside. I got a T90C gearset that has a lower 1st and 2nd.
This thing is worse than a TJ, it needs everything.
Look at those tinny, thin, delicate little rings.
This wall is a little scuffed up, the others are better. All have a ring ridge. My local guy can't bore it as it's too tall of a bore. I believe its 7 or 8 inches from the deck to the bottom of the cylinder wall. So, I'm exploring my options.
That's out of my wheelhouse, I assume his machine doesn't have the stroke to do so, but just thinking, Why can't he bore the bottom first, then bore the mid and upper area last and finished it like normal? I know that's not typical, and he'd need to know roughly how much he's cutting out up top, but maybe it's a way around it if you like that guy/shop.
Yeah, I think it's the depth. His boring bar only has a limited depth for the diameter. It's a goofy engine. Small little bore and tall walls.
Yeah the bore is 3.125", and the stroke is 4.375", but the piston is 3.75" tall as well. So like a 8" wall with a 3" bore. I have a CNC that would probably be able to do it, but I have never bored an engine, and I'm a little hesitant to ruin this 80 year old block.
Welp, I decided to take the chance and bore it myself. It ended up being way easier than I thought it would be. All the scuffs and ring ridge cleaned up at 0.020" over. I bored it about 0.003-0.004" under size so the machine shop can hone the pistons to fit.
I've made a bit more progress recently. The engine is rebuilt and running. I started reassembling the frame and drivetrain. The tub is getting a few rust repair patches and some new subframe sections. It should be ready to set back together sometime this week.
What's up with the rear drive shaft running past the rear axle out into space ?
That is a pto. You can see the rear driveshaft is offset like the front
