Heater hose swap question

Hi all, I'm new here. I have a 99 4runner 3.4 SR5. I recently bypassed the rear heat because it wasn't working and being in the rust belt I didn't want to deal with any potential future leaks.
I looped the rubber lines with a barbed union where they tie into the steel ones at the firewall. Looking at it now I'd rather just clean it up and get the proper non-rear heat hoses that go into the control valve and out of the return.
Can someone point me in the direction of the hoses I would need to eliminate the T's that feed the rear heat lines? Thanks in advance.

And while I am at it can someone give me the correct way to replace the rear shocks. The nuts on the top are rusted and spin the whole tube when trying to undo them. I'd guess that I need a locking strap wrench of some sort to hold the tube and try to get the nut off. I even tried to just cut them but couldn't fit my sawzall in the tight space. Thanks

The rear heater is a very easy to diagnose system and kinda handy, if it ain't leaking it can be made to work, or you can get the 01-02? SS rear rad lines, maybe the heat control cable is outta place or the door is jammed up.

Cut the shock shaft at the bottom of the shock tower with a grinder and zip cut blades and/or twist it back and forth till it snaps.

Thanks for the reply, I'd just like to go without the rear heat and not deal with it. Are there hoses that replace the ones with the metal T's in them? If so can you point me to which ones? Thanks, much appreciated.

I recently deleted my rear heater to make more space under the passenger front seat.
I ordered the correct heater hoses for the non-rear heater version of my year 4Runner.
You can see them on any of the internet parts dealers that we all order from. I got mine from Amayama, because I judged the Toyota USA prices to be over-inflated.
The drawing you will work from will look something like this.
Note: This is for my '97...make sure the drawing you work from is for your 99.

Thanks, to me it looks like I need 87246A and 87245A, how hard is it to get to the connections behind the engine. I'm assuming that is where they go but I have not looked yet. thanks

The connections are all visible, but access is annoying, at least to me. I sloughed the job onto a tech who was already doing the timing belt/water pump, valve cover gaskets, and oil cooler hoses and o-ring. I think he charged me 1 hour labor. (It would have taken me 2-3 hours of suffering to do what he did in an hour). I had bought the parts ahead of time.

I took a quick look back there tonight. It is tight but it looks like the clamps can be reached with a pair of long needle nose. Possibly put a little lube on the new hose so it slides on easier.
Looking around I think I'm just going to go with the silicone set of three hoses that they sell. I think the price is the same or very close to using OEM hoses at that point. The silicone kit comes with the screw drive clamps, does anyone know if you can use the stock constant tension clamp on the silicon hoses?
This is the type that I was looking at. I just don't know if the OD of the new hoses is the same as stock so the stock spring clamps would work Anyone who has these please chime in. Thanks
