New oil pan has been installed with fresh hardware, and man cleaning the RTV sucked... never doing this job again, a shop can deal with that LOL. Removing the OEM header was a challenge because the bolts were corroded due to heat and salt. I ended up cutting the overpipe at the flange and picking up a replacement. Fresh Grimmspeed/Vibrant gaskets will be used, as the 243k ones were a bit past their prime for being reused.
While the pan was curing, I installed the Bride Zeta IV seat on Bride FO rails, more black interior trim, and a GCS 4th brake light. Currently the light is only wired in for reverse lights, as I decided I want to build a harness to tap into instead of splicing into the car's wiring.
