So everything went well, I followed the guide in the link I posted above and started Driver Rear, Passenger Rear, LSPV, Passenger Front, Driver Front, and everything ran clear. I can tell you it was about as funky as brake fluid can get, Kauai red dirt or rust hard to tell, but chunky and funky. Cleared out the lines and topped up with fresh Dot3

I used the one person method with bleed bottle made from a medium sized water bottle. One hole in cap to fit snug clear tubing in 3/16 i.d. and one small hole for venting in the cap. A zip tie on the inside of the cap holds the tubing from pulling out.

Old fittings can leak a little air around the threads so it's good to either pack around with some grease or just barely crack them.

Glad it's another couple years before need to do again!
