help!

I've run into a problem here with my Dahlia Cardigan - all my own fault. If you don't know anything about the construction of this cardigan, it's a little different than anything else I've made. Without going into too much detail, the sleeves are done as an afterthought thumb hole is done. Scrap yarn is knitted in, and will be removed, and the live stitches picked up for the sleeves. Here's my problem. One of my mods was making the back longer, so I added 8 stitches to the bottom. When marking the first sleeve, the stitches are counted from the bottom. Example - the instructions were to knit 60, then add in the scrap yarn. What I realize now, after I've finished that entire side and have started on the other, is that I forgot to account for my 8 extra stitches on the bottom. So my scrap yarn is placed 8 stitches too low. I realized this when I placed the scrap yarn for the second sleeve and they were uneven. So, my question to you, dear fellow knitters, is HOW can I move my sleeve to the right place WITHOUT frogging back the entire right side?

If you can't understand my jumbled mess typed at 6:30 am on a Monday (and I don't blame you if you can't, I definitely don't have time to edit this), here's a photo:

Not the best photo, I know. Right under the words "scrap yarn" is the yarn I knitted in for the armhole. I need to move it to the left 8 stitches without undoing that entire side. I have a few ideas, but want to hear what you guys have to say - especially if this has happened to you too!
