Sorry to bring this old thread up, but I have been searching for a trunk spring tool myself and have had some trouble. I checked many sites and called several dealers. Acura of Augusta was the only one that seemed to be able to assist me. The new part # for the tool is as follows 07AAF-SNAA100 (old one was 07AAE-SDAA100), it's $21.77 plus shipping & tax (should be around $30). I have not purchased it yet so I can get some feedback, maybe someone found it cheaper than this. BTW he stated that it may take several weeks for the part to get to me. Any thoughts?
