I'm looking for a source for parts for a Delta Model 28-274C band saw. Specifically the lower blade guide. I was going to do some resawing today and changed blades on my band saw. After I got the new blade in place, I noticed that the blade guide on the right side of the blade was loose. I inserted an allen wrench in the set screw and just as I moved the allen wrench the block holder fell off the saw in two pieces. I'm not sure what caused it to break, but I now need a replacement. The part is die cast aluminum. The part number is 426-02-355-0004S Lower Blade Guide Assembly. All the sites I have checked thus far saw the part is discontinued. These include:

I have seen some "upgrade kits" from Carter and sawblade.com. Are there other OEM parts or replacement sources I should consider?
