What capability do you have to roll the rear end and change the caster? Would that mess up driveline angles or not possible?As Mike said 3 thirtytooths ain't much, did you see what I was talking about graphing it as he shows. That tells you what to do to adjust/correct it. You seem to be on the right track with setting it at 0 to 3/32 toe in. That is now going to be only 3/64ths at ride height which is pretty good methinks. Morris did a heck of a thread and explanation of setting up that geometry for an IRS on the Gasholes forum. Worth finding and reading if you have a spare hour or two.
