Looks almost identical to the 4th gen 4runner. I had their ladder on my 4th gen 4runner and would not trust putting a full size spare on the ladder. The mounting brackets are held on by basically double sided tape and some pressure screws @GXLee
I'm currently in the process of this job on my 4runner and hope I don't have to ever do it again. I would like to know the thought process of the person that decided on the location of the thing... and more so the bolts that hold it in. Any tips on getting the bolts??
I'm actually looking into doing the same thing with a work body bed. Ideally off something like a Tacoma so it is about the same width/wheel base as either of the 120 series it will be towed behind
