Spare Tire Carrier Extension

Is there a replacement for the '02 spare tire carrier that would allow me to carry my spare 35''x14.5''x15'' tire and rim... totaling about 100lbs.? I don't want to replace the rear bumper because I already have the chrome tubular "Urban Defense" bumpers. Thanks

not sure if this is exactly what you are looking for, but the description says that it will fit 87-06 jeeps, and will hold up to a 35" tire, in the stock location.
