I just talked to a guy today that works for the same company that I do and he says he has about 300-400 toyotas he sells for parts. Then he tells me he has 2 wolverines, and half a trekker. He says the trekker does not have the pass through to the back but has the winnebago sticker under the dash.
I am going out to his place on Sunday so I will take some pics and let you guys know what I find.
Wolverenes were produced from the 78 Hilux years using dana diffs , and spicer transfer ..... 79--83 toyota had there own 4X4 , and a "Trekker like" conversion was done ... the elusive one ... this is the one were looking for! /84 .. they were still converting ... a "4Runner like" conversion ..
There is a picture of a blue one and a yellow one with decals, mine was yellow much like that one. My uncle still has it too! Sorry I don't have any pictures to post. Let me know what you think, maybe I'll end up getting it back from him!
