Still need help with obsolete parts for Roper cooktop -


"We have a gas (propane) cooktop - Roper Model C2757 - that was here when we bought the house and is at least 15 years old. The left front burner began to burn orange and soot the bottom of pots. I took it out and found it was beginning to rust out at the base of the burner where the gas tube inserts into the bottom. I've checked online and can't find this part (310303). Most say "no longer available" . Does anybody know of a source - new or used?"


Any help would be greatly appreciated...
