I just recently did a 10 bolt. I used a plasma cutter. I suppose a sawsall and a grinder would work. The trick during all of this is to not distort the tubes when you do the job, no matter what removal method you use. No distortion from a hammer or from heat.

As for the spring perches, spend the $20 and get some from www.currieenterprises.com or www.chassisengineeringinc.com .
