Yep, not really surprising to me, though. I hired mine done at a truck place the first time to get the stock height ones in, so no drama. Second time was just testing the much touted Erb springs, which were maybe .25-.50" to tall to put in with compressing, which really complicates the job. Local frame shop said not problem even though I told them how big they were and that they would need a BIG spring compressor. They mucked around all day prying and hammering and did get them in without compressing (their compressor was the strut type do wimpy) albeit very dangerously. They tore both ball joint boots and gouged up lots of other stuff. The Erb springs were junk, so I bought the big compressor and put the old ones back in myself. Putsy with the compressor, but if not working off the floor, on stands, would not be horrible.
The Moog springs are listed as stock height, so if they had trouble, they must have been longer than listed. Stock height ones can be done in a very short time. The truck shop did the stock height ones in about 35 minutes for both with another 20 minutes to align it.
If you are doing a spacer lift, you will also need the spring compressor as you have to compress the stock spring over an inch to get the spring and spacer back in to the deep upper spring pocket, so that would also be a PITA.
