Green Plastic Standard Seed Bird Perch - 3-Tube Super Feeder

I have had the 3-tube Super Feeders for the past 20 years and I love them (I had to replace the 1st one after 15 years or so). The feeder came with 1 seed perch made of metal and it has lasted through both feeders. BUT, the squirrels (who have a squirrel feeder with peanuts right next to the bird feeder) are able to chew the plastic ones and get them out. Can you sell the metal ones as replacement parts? I LOVE this feeder, most importantly, the birds and squirrels love it too. We registered our yard as a Wildlife Sanctuary and the 3-tube Super Feeder contributes as a wonderful food source for our wildlife. Thank you North States!!

These should be metal so the squirrels wouldn't be able to remove them. They chew right through these plastic ones.
