Rob, I have the A20's in my boat. They all break every now and then.. I had to replace one when one of my old IMCO's decided to check out and lock up and spit the u-joints out... 
Since they're steel it makes alignment a little bit more difficult than the alum. but no so bad... After re-rigging my engines and doing the new L-angle and drilling, doing the alignment was pretty easy. Also, alignment was done with the regular Bravo tool.. If you have ITS you need a different tool, otherwise it's the same.
As for yourself, you have offshore mounts so there's not really any alignment you need to worry about. a 1/16" wont show up on the alignment tool. The best way to check that you are going to be ok with offshore mounts is to check run-out on the coupler before you install the engines. If you're alignment changes drastically when you're bolting the offshore mounts chances are the alignment wasn't perfect to begin with.
