Toe in adjustment
Okay, I know there other adjustments, camber and caster, right now I want to get the toe in as close to what it should be which I believe is 1/16 in. I got it as close as I could using 1/2" EMT clamped across the front of the brake drum hub assembly (should have taken a picture). Then I measured from the outside of the frame to the center of the conduit to where I was as close to 1/16" toe in on both sides. What are some of the ways others have done this?

Toe-in is measured at the rim of the wheel. You need to measure at the front and back of the wheel to get the difference. If you can find a wooden dowel that fits inside your EMT, and mark where the dowel sits at F&R, it will be pretty darn close.

I should have explained better, the EMT conduit is long enough to where I can measure both front and rear from the frame to the center of the conduit. I just went for a drive, it steers fine but likes to wander especially in a curve. I have some 15" wagon wheels, I had to use 1/8" spacers because the drum would hit the inside of the wheel before it was seated against the drum/hub. With the wheel and tire off I use the spacer to clamp the conduit to the drum/hub. Looks like I still need some fine tuning.

You need to measure tire to tire, not drum or hub. The frame should not be in your equation at all. And if I read you post you had 1/16 toe-in each side, that is 1/8" total, which may be fine depending on suspension, tire size and type (radial v.bias).

Thanks guys, never thought about weight of the truck and the other considerations, so I'll give it another try and see what happens with the tires mounted.

Adjusting the toe-in has already been explained in detail here, so that’s the first thing you should do.
If the vehicle tends to wander off course or the steering feels twitchy, this could be due to your wheel spacers, for example.
These alter the steering roll radius, so you should also make sure to install wheels with the appropriate backspace.

When I had a race car I used something like this. Actually just a couple of pieces of steel or wood and 2 tape measures. Put the edges of the tape next to the tire. You want them at the same height off the ground on both sides of the truck.
