The permanent fix:
The ratchet strap lasted me 2 weeks until I got parts and time to install them. The new OE part numbers you will want are:
77601-35110 - Front strap
77602-35050 - Rear strap
Which can be found on this diagram and come out to be about $90 before shipping: https://parts.conicellitoyotaofconsh...omponents-scat
As it turns out, the rubber fuel tank protectors are included with those part numbers as an assembly. Now, there is a non-oem kit on a few websites for a bit cheaper. I decided to stick OE, they lasted me 11 years after all. If you get an aftermarket variant feel free to let me know and post in this thread, I'm curious what they look like.
Here are what the new parts look like, I decided to just do both while I'm at it.
First you will want to remove the fuel tank shield retaining strap as noted in the picture below. I have no idea what this thing is actually intended to do but it makes life easier if you remove the 2 nuts from the body side. (circled in blue)
Then you will want to go ahead and remove the plastic fuel tank shield. There are 4 nuts, 2 are pictured below. Before doing so you will need to carefully remove your method of supporting the tank. (if any) In my case I took off the ratchet strap since my fuel level was practically empty and there wasn't a whole lot of weight.
Here is what it looks like fully removed including the retaining strap:
Once removed, use a jack to support the tank and push it back up a little bit:
Then remove the pin from one side of the strap, located near the center of the vehicle by the driveshaft:
Then unbolt the remaining side of the strap, this bolt was a pain for me to remove because how the bracket is constructed it sits in water and mud its whole life. Spraying with WD40 or something better makes a world of difference. You can easily shoot it horizontally inside that welded-on bracket and cover the threads inside the frame.
Finally, install the new strap! Exact procedure but reversed, nuthin' to it as I'm sure you are an expert by now.
You may need to jack the tank up a bit more to fit the new one on.
When you have that strap on, repeat for the other side (if you choose to replace both) and relocate the jack as necessary to support the tank.
Once finished reinstalling the plastic shield, and you've double checked that you bolted on the tank shield retaining wire doohickey, grab a cold one and enjoy your hard, money-saving work!
