I have a 2001 Olds Intrigue that I am trying to bring back to original condition/like New. I would like to replace the sub frame insulators. The front insulators are still available through GM, however the rear ones are not. I have yet been able to find an after market part for these parts. Can any one tell me if they know of a after market manufacture or if another GM model car would have the same or close to the same part. Dorman P/N 924-007 looks really close to the right one but height dimension is not the same. They do not make the rear insulator for some reason. The GM P/N I'm looking for is 10249731 and 10414244.
