GE Profilt XL 44 Gas free-standing range

Question

Hi,
I have read some of the problems with this stove and I would like to report I have had my stove for over 8 years and not one single thing has ever gone wrong with it. It has been the best stove I have ever had. The oven is the most accurate of any oven I have ever had and bakes everything to perfection. What I need is a replacement oven bottom. There are screws that make me believe it can be replaced. My son in law was cooking and spilled liquid in the bottom and after it was baked on he tried to scrape it off with a knife and scratched the bottom of the oven beyond recognition! I am moving and leaving the stove in the house but would like to repace the bottom so it doesn't look bad. I can't find the part anywhere - can you help?
Thanks, Debbie
