Princess electric stove

Shortly after we purchased our 44' Gulfstar 2 1/2 years ago we had the galley refitted with a new Princess 3 burner electric range. The drip pans or bowls under the burners are rusting away at an amazing pace. They already are beginning to look terrible and at this rate will soon be dangerous to use. They are "built-in" to the stove top -- they cannot easily be taken out for cleaning, etc. -- but I believe they can be replaced although with some effort. Problem -- we can locate no retailer who stock the parts. We can easily get a complete new stove and have located drip pans (bowls) for the Princess gas ranges but for the electric, no.
Any ideas as to where we might find these and also any suggestions to slow rust in future appreciated.

I just replaced the drip bowls on my Princess electric. If you post a picture of yours, I can tell you if they are the same as mine. KJ

Try Camping World ,they have a great huge parts dept, these are RV units.
