| Yes it's two sides of the same coin. With an adjustable rear wheel you are using the front as a reference, but on the 748 etc the rear wheel is non adjustable so you are using it as a reference for the front.
Using the string method and a steel rule, you should be able to achieve an accuracy to the nearest mm (make three measurements and mean them), and the dimensions should be identical on each side. If it all measures up, then its a good indication that all is well. If it is out you will probably need more specialist equipment as Frank suggests.
