do a bit of searching around but:--->
Will a T series complete rear axle bolt straight into a ke70.
yes yes it will
i understand the 4 link mounts are all the same, BUT what about the tailshaft/diff yoke?
you need a rear T18 tail shaft section
Does the s series tailshaft go straight up to the t-series?
no, read above
How much bigger/stronger is the t over the s?
i don't exactly know, but i know they don't hold up to well to turbo applications, or even gze's.
pretty much no other diff will bolt in at all, hilux etc is all custom, it has been done a few times and can be done relatively cheaply (1000$ or so, withouth LSD) but some are hard to get LSD for.
plenty of info around!
