I knocked out a few more small items this afternoon while the boys had their nap:
Cleaned up (with a grinder) the cuts to make sure I didn't have any obvious sharp edges.
Spray-bombed the cut areas with rust inhibitor / paint.
Took the dash bar out and cut off a couple of brackets where the stock dashboard mounted to. Without the dashboard, they turned into knee-spears, which was always awesome as you were getting ready for an autocross run.
I cleaned those cuts up as well and smoothed them down, then gave the whole thing a couple fresh coats of rust inhibitor / paint, mostly to clean up a few spots where bolt heads had rubbed the paint away.
