After looking at the rear heater hard lines, by passing was a must. Hit pause on everything, ran to the parts store for a couple feet of hose to finish the hose overhaul. PHH was a real monster...Im a pretty tall dude which didn't help either. Long arms helped a bit but either way that thing sucks. Highly recommend using a 90 deg bent pair of needle nose pliers to get the last clamp off at the block. As far as removing it, after undoing the 12mm lower bolt on the metal tube/bracket that runs up to the heater control valve I took a sharp knife and cut into the tube. Then followed it up with some dikes. Once at the factory Toyota clamp, I just hacked through it and cut it as turning it in that area is highly unlikely. All in all it was a pretty smooth job, took some time but the piece of mind is well worth it.
Few pics of the job for anyones ref need. I can snap some more as well for the rear heater bypass if anyone wants it. Highly recommend bypassing that thing as it is likely cancer infested. Huge thanks to @beno and @Houston FZJ80 for the quality parts and info.
Note the photo below has the normal hoses on, and not the bypass. I pulled off the lower small hose after finding pretty good cancer on my rear heater lines. Swapping it for a longer length to by pass and go straight to the firewall.
Do you guys see the slight angle of the hoses being an issue? They are not being forced or pushed up, simply how the hoses sat. I would imagine over time they will settle and come a little more horizontal. I can imagine they will be an issue, but worth asking. New heater control valve, new green stripe hose on top there and white strip below ( parts store only had the white ).
