I just replaced the starter on my 69 Z last fall, and now I think it is failing. Starts fine when cold, but when the engine has been running and is hot, nothing. 2 questions: IS there supposed to be some sort of heat shield mounted with the starter, and if so, is heat causing this early failure? Or did I just get a faulty rebuild? Car is driven weekends, nice days. Probably started no more than 30 times since I replaced the starter. I do have the bracket installed on the end of the starter which adds support and takes cantilevered load off the 2 block mounting bolts.
If I need a heat shield, who would supply? GM NAPA? I'm concerned with function not originality.
