Reliant branded tools were sold by a Boston based woodworking supply company called Trend Lines. They had quite a few stores in the North East part of the US as well as a catalog sales business, but they closed their doors sometime back about 1998. Their Reliant brand tools were all Taiwan built and very similar to many other Taiwan made woodworking tools on the market at that time, so many parts for other brands of similar Taiwan made tools will likely fit, no matter the tool color or brand name. It's quite likely that all of these tools came from the same tool manufacturer in Taiwan and just painted or branded differently depending on what their US customer wanted.
If it's parts that you need for your sander, look at other brand names of the same sander and the possibility of ordering parts for that brand name sander. They will very likely be a perfect fit. I own a Reliant 18" band saw and may need to do this same thing some day. My first search would be Grizzly Tools or Shop Fox to see if their tool looked the same as mine. Woodtek is another brand name of Taiwan made tools that are sold through Woodworkers Supply. They might also be of help in finding the needed part.
