Oh MAN! YOU DON'T DO THAT!!!!!
Yeah those sixies are probably the most indestructible and torque ones out there and on Toyota's six, if your water pump goes out fix it don't run it some more!
Hey, it pays to know a guy that has owned these since my dad knew him, 70's and 80's, maybe 60's? I think, not sure I think and worked with him, he's ALL Landcruisers with his sons mainly FJ40's and other FJ's and Toyota pickups, and I think that's where my dad caught the Toyota bug.
Ok, nevermind then! It sounds like you're good in parts stores!
KEEP IT UP!!
