I annealed the springs and used the barrel sander on my dremel tool to take down the spring thickness.
I took down the overall thickness of the spring by about 25%.
I used the polishing wheel on the dremel and some buffing / polishing compound (silver color, I don't remember the grit). It took about 15 minutes to polish both springs. It probably would have taken 5 on my old polishing wheel, but my wheel got mislaid in my last move.
I retempered the springs and they are cooling now. I will let you know how the installation goes.
Thanks for everyone's help.
