i saw a sweet coolant overflow resevior that brian soderblom used on his bronco so i went to the yard to find it today. I got super lucky and found a 94 gt mustang...how sweet. I pulled the reservior, but i noticed it had a crack in it. it wasnt too bad so i bought it (2.50 because it was cracked). i was wondering what i could use to patch it. i was thinking just like silicone or something. maybe a gasket sealer?? any help would be appreciated. thanks.
