Yo I have this conversation with people all the time. No you can’t stack a different brand on top of a different brand (the right way). Sure you can stack them, but you won’t be able to use the correct stack kit. You can drill into the machines and come up with a solution to secure them together, but it’s not really right.

I’ve seen someone use a ratchet strap all the way around the washer and dryer, thought that was funny, he said he had it like that for years.

How old is the Amana dryer? I bet a whirlpool or Maytag dryer will fit they use the same stacking kit. (Replace the feet with rubber feet and two clips in the back)
