I have a 92 Loyale that needs new wheel cylinders, it is 4wd and has the strut type brake adjuster. There are two different sizes a 11/16 and 3/4 on the wheel cylinders. Is there anyway to tell which size I need without taking one off? No one has them in stock so I have to order them and since this is my only means of transportation I can't really take it all apart without having parts to put back in immediately, and I can't order them without knowing the size. Thanks for any help.

It should say on the outside of the old cylinder. Your car should be 3/4"
