a properly built straight car should have the same length trailing arms on each side, but to double check the best most accurate way is to run a plumbob off both lower balljoints and mark the spot. Run a plumbob off each side of the rearend and mark that spot then measure the distance between the 2 spots. When both measurements are equal then the rearend is square to the frontend. Now that you know your rearend is perfectly square you can measure your trailing arms and see if they are the same lengths on each side.

Make sure caster is the same on both sides before measuring from the bottom ball joint.

caster wont effect anything because the lower A-arm is stationary.

Another way is to place a pin in the center cross member and string the rear end to equal points on the rear end (brake disks). Make adjustments in the rear end to insure that the string is equal length on either side of the housing. This will center the rear end relative to the center point of the front cross member. You should then mark and measure the distance from the front of the rearend to trailing arm connecting point. Then with a string on the outside of the car, parrallel to the chassis, set the offset of the rear end relative to the center line which is specified (ie flat along the left side). This should have it. After the adjustments are made make sure your trailing arm lengths are correct (back to the first step) and double check all measeurments.

i think 2nd has a good way , we also do it the same way, the only thing we found is make sure the bushings in the lower a arms arent worn out like ours were and making everything mesure out wrong

i agree with you zero that cars are using different length bars on each side. The whole idea is to get the rear wheels square to the front wheels then adjust from there.
