Align the IFs first. I can't remember, but I believe one of the 90 series versions lacks AVC. I recently used a scope. See my thread here

Not saying this true on all sets. But, it sure made me a believer on the accuracy of the IF alignment. If it lacks AVC, you can use the plate of the output tube. It's explained pretty well in the thread. You can even use a VOM for this.
