coolant tank. :(

I won't argue with you for paying to have someone do it! I got to that point, almost. I gathered my composure and went at it with a different approach... and it worked! My frustration was with getting the new one back on! Getting the old tank off was definitely a PITA as well!
I did find one tool that helped a lot! extra long needle nose pliers! They enabled me to reach the spring clamps. I was able to reach them through the wire harness seal. I took that off and moved it enough to get the pliers in there. I was able to locate and remove a few of the camps that way. Once I had a couple of them off I could then pull the tank into the trunk area enough to get the clamps from the trunk side!

Dear Tony.
We all feel your pain.
Every one of us went thru the same frustrating moments at this point or another.
I would like to give you couple of advices before you give up.( And believe me, I was on the way to the store to get a case of dynamite more than once).
1. If it doesn’t work for you, walk away. Start over fresh tomorrow, I promise things will look different.
2. Take bmx672 advice, and replace the hoses as well.
3. Get that tool : Amazon.com: Astro Pneumatic 9409A Hose Clamp Pliers: Home Improvement
No clamp is slipping any ware with that.
Good luck bro. just think of the satisfaction you’ll feel once you will complete the job

Sears has them too. And I agree, don't try to open the clamps without a cable operated tool. The whole Boxster is inundated with these hose clamps, the tool will pay itself back in no time. I wouldn't have been able to replace the AOS without it.
