Rear wheel alignment off?
Is having the alignment of the rear wheel too much to one side an issue when riding for any reason? I just installed a powertap campy freehub to replace the shimano one I had on there, I've done everything I can think of, taken spacers off, put some on, tried different size ones, but can't seem to line it up. Anyone have any tips? Taking this to a bike shop is a last resort for me because I work off shift and like to do mechanical fixes on my own if possible so I can learn. As you can see from the photo the wheel is too much to the left, although when spinning it does not look off true or anything. I believe it's a spacer issue but I can't figure it out and the Saris instructions are absolutely no help at all.

Looks like it’s not dished correctly did you just center it on the hub? if so thats the problem.

Seeing it may be better than just trying to explane it look at the wheel on the stand its off set. https://bicycletutor.com/wheel-truing/
About half way you'll see a rear wheel on the stand note that it's not centered on the hub this is the dish if you don't quite understand this part it may be best to take it to a LBS and get it done.
I'll add that its like this because of the hub on the drive side hope this helps you understand it a little more.

If you want to try it yourself loosen all the non drive side nipples I'd guess about 3-4 turns for starters the tighten the drive side this will move it over closer to center in the frame do this till its centered then start truing again and set spoke tension keeping it centered in the frame, but if you don't have the correct tools of basic idea take it in and let someone correct it for you.

I figured it out thanks. It did in fact have to do with the spacers, after playing around with it some more I was able to get it centered as it was before I swapped out the freehub.

Doing it with the spacers isn't the correct method now your chain line is off, but its your wheel and if thats what you want to do I guess thats your choice.

Unless the bike is a single speed the chainline will only be straight on one gear, any shifting and the chainline is off. The deraileur is always centered under the gear being used at any given time.
