Just got her 79 750 LTD the guy put a lot of time in to her custom everything. 430 mile the dam chain came apart a 65 put a small hole in the case. How would one fix this hole it is smaller than a dime. J-B weld?? It still had oil in her when I got her to the side of the road didnt do much but the hole. I dont no if there is high presure in the case or not.
