I stand corrected, GMC was owned by the same company that owned Triton. This doesn't change the fact that Lowes has a pretty good track record of supporting products it sells. This is still the first place to try and find parts. As far as parts interchange goes I understand your point James but some parts are common in manufacturing. There are many bearings, light bulbs, screws and fasteners which turn up in competing brands, even some major components like axle assemblies. The old PC 1-1/4 hp router that came with the overarm router I bought didn't have a thumbnut to secure the motor in the base. It had been replaced with an Allen screw and starnut for clearance. There are a limited number of threads to be found on most screw sizes and I replaced it with the thumbnut and bolt off a PC 7518... a perfect fit. I attached photos of a Bosch 905 router motor in PC bases as another example. Collets have a limited selection of threads and tapers to work with so there is a good chance another collet will work.
