Was going to mention that the addition of a battery disconnect for about five dollars might give a slight amount of peace of mind until you get that thing repaired but suspect might take too long to get hood open and starter turned off before damage occured. Might be an auto wrecker near you with reasonable prices for a used starter and even willing to guarantee it somewhat. See them sold used on ebay once in a while for about 20-25 used as well. Plus shipping unfortunatly. Scrounge a little.
