I just finished re-doing my shifter cables. I put all my nuts and bolts and rubber pieces for the cables in a box that my son decided to put out for the trash man. My question is this...I found all the bolts in crap through a junkyard sweep but i don't have the rubber or bracket for the firewall. Now, all the fumes is getting into the car from the engine bay. Is there some automotive foam or sealant i could buy from advanced or pepboy?
