Trying to cram in as much as I can through the holiday before people start expecting things of me again.
Short of the bracing between the two towers, I think I'm done with most of the chassis fab up front. Got some gussets added to towers, final welded everything with them, got some paint down.
Lower radiator port has been relocated and clears the steering box beautifully. Waiting on the new water pump outlet to arrive so I can figure out how to plumb between them. Radiator, intercooler and condenser mounts are all finished up. There will be another couple of brackets that tie the combo into the fenders, but until they're back on I can't design them.
I was able to shim the steering box and gain a little needed clearance between the steering joint and the strut tower.
Took the knuckles off the axles and confirmed some measurements to have the inner shafts shortened. I think the issue was a miscommunication since they're almost exactly 1.5" too long. My initial measurement was from the crosspin, and I'm thinking maybe the builder thought that was from the outside face of the gear, since the ARB has 1.5" of spline engagement. Need to get the joints removed but Dutchman said they could turn them around quick.
Found a sweet exhaust flange for a different application for this motor that exits straight out of the rear with a v-band, and for just $38 straight from Cummins. I'm still amused at how cheap parts for these little engines are. Plan is to run 3" from the turbo all the way out.
Scoured Donaldson's parts catalogue and found an air cleaner that I should be able to squeeze between the motor and firewall. Necked up from 2.25" off the turbo inlet to 3". The air cleaner has 4" fittings on both sides, so I'll do 3" into the turbo on the filtered side, and 4" from the snorkel in. Cummins calls for 300CFM for these motors, and this one flows 494CFM, so even with all the snorkel plumbing I should hopefully have plenty of air.
Project of the day was front sway bar. Tony at TK1 was super helpful in figuring out some details. It's tighttttt on the drivers side stuffed at full lock given the outboard steering box, but I think it'll just barely squeeze. Going to run the bar through the front chassis crossmember since there's practically nowhere else to fit it, but my ****ty little sketch in CAD seems to indicate it'll be ok.
