Query: Beam cutter not compatible with DeWalt DW378G

Although this product is advertised as working with "ANY 7 1/4" Worm Drive Saw" I discovered the blade guard of the DeWalt DW378G prevented the installation of the Beam Cutter. Upon talking with the manufacturer I found they were aware of the problem and had no plans to modify the product as they would have to change the head casting. They also pointed out that the DeWalt model was a hypoid drive and not a worm drive.
