Swap info that just came to mind:
Intercooler piping. I used a 2nd gen intake, but with my A/C i had to cut off the "wing". Cut up and welded the left and right hard pipes from a 2nd gen to make one single pipe on the driverside, and used the "S bend" passenger side pipe from a 5.9CR on the passenger side cut to length to mate up to the 3rd gen manifold and HE351CW.
The trans controller was actually far easier to install than I thought it was going to be. All it needed was power, ground, and to run the speedo wire from the controller into the DK GRN on the VSSB behind the glovebox. Rest of it is plug and play. Be sure not to chop all of the wiring to the trans though. I almost did that because the claims made all over the place that "all it needs is a controller to work" are TECHNICALLY correct, but the NSS controls all kinds of other stuff.
With the [modified] 2nd gen intercooler in place, the lower marker lights need to be clearanced. in order to mimic the bulb holes that were removed to make room, i used a step bit, then hand files to get that indexing/locking slots for the bulb socket.

Alternator. I'm currently running a CS130D and that drives the tach on the dash like normal. I believe it's off as that alt signal is for a 8cyl, but it's fairly close. It reads about 650 idle and I believe a Cummins normally idles approx 750. A pulley change will fix that. as the CS130D is only a 105A alt, I'll be moving to a AD244 to support the elec cooling fans, Hella HIDs, and other electric accessories.
I should have dynamat-ed my firewall before reassembled.
