I made some alignment bars the bolt on to the lug studs. I have them marked in the center and on each end for my tire size. With them bolted on I take a measurement on the front and back marks, looking for a 1/8-1/4 inch difference, smaller in front for "toe-in". I have used this method all of my life on go-carts to top fuel dragsters and all solid axles in between. Toe-in is the only easily made adjustment on Toyotas!!
