Kaufman Tool Repair, the GoTo site for those very hard to find parts. Found a replacement spindle for a SawZall 6507 that allowed a Quick Lock Clamp. No more allen wrenches, yeah!

What a breath of fresh air it was to work with these folks. There was a question as to whether the part I ordered was the correct part. Instead of just shipping it and hoping for the best they reached out early and prior to shipping to make sure I was getting what I needed. Shipping was fast and they followed up after I received it to make sure it would work for my needs. Awesome small business to work with.
