@mblakec you deserve a community service medal for the highly detailed part #/diagram info in this thread…or maybe a park bench dedicated in your name with a view of your favorite mountain range! Good stuff.
I plan to refresh the entire top of my 3FE this year to include a complete heater hose complex replacement. I replaced several heater hoses w OEM numerous years ago, but used crappy over tightened worm gear clamps. The other hoses are still original (35 years!). It’s looking ugly in there these days.
Since then we’ve lost several Toyota parts guru guys that helped us find all these little things and some things are NLA now.
Working on my list now. And I’m going back to the OEM double banded wire style clamps all around.
