I am in the middle of rebuilding the firewall forward on my Sierra. When removing the firewall, several of the cables had fittings on the firewall that waterproofed the cable firewall intersection. When removed several fell into pieces. I have been unable to find any part numbers in the catalog. Any help would be appreciated.

Also I am not finding alot of information about the replacement of the insulation and fabric that was on the inside face of the firewall and the pedastal base. All ideas would be appreciated.
