Even if you could check each side independently, the two are forever related by the tie rod. One side reads 1/16" and the other reads 0 then the difference between the two would be 1/32" toe in.

I would raise the front and check for any sign of loose spindle bearings first & foremost. I'd then rotate each wheel and check for any sign of wobble due to a bent wheel. This kind of stuff can make it hell to try and properly adjust the toe in.

The caster and camber are harder to adjust without axle or wishbone bending tools but radials should do OK with factory settings as long as the axle & radius rod are still in good condition.
