I saw and worked on the cat Saturday. I didn't take any meaningful pictures, but I needed to buy a low mount Corvette alternator bracket as the OEM one on the top was touching the ABS unit. Got it from LSsimple.net which were the only ones that made a lower bracket to use with Corvette accessories and Corvette alternator (Vette accesories run 3/4" offset in compared to any other LS motor accessories and the bolt pattern for the alternator is different than for any other LS motor).
Aditionally, installed Fullblown slim fans and shroud for more room up front. The OEM fans would have been able to be used but needed a bit of shaving on the fan mount. It seems I have plenty of room to run the AC and heater lines on the firewall.
Lastly, it seems the 1/4" spacer on the mount coupled with some minor notching on the oil pan will allow me to keep the sway bar.
The oil pan relocator fittings will need to be cut and welded with hard 90s to clear the subframe.
