Replacing front disc brake caliper Bolt alignment?

I've done this job three times now. Every time I try to bolt the caliper to the bracket, the two mounting bolts will not line up! One goes in and the other will not! I watched this video hoping to get a trick to help align them and I was amazed to see how easily it worked for you. Today I spent hours jiggling my caliper back and forth trying to get it to go in. In the past, if I finally get the angle exactly right, it goes in. It's a very frustrating process. Has anybody experienced this and what advice can you give to help?
