My rebuilding project has been held up by about two weeks for want of the correct stud used to bolt together the engine and transmission on my 69S. Three of the studs are the same but the fourth one is longer because it goes where the starter is mounted. This longer one is what I am lacking. The stud is a M10 type but has to be about 110mm in length. I haven't been able to find this size at any of the usual sources such as Pelican, etc so I was thinking of just ordering from a non-Porsche source like "Bolt Depot." They don't have metric studs but do have metric bolts. To order properly you have to specify the thread count. A standard thread count is 1.5mm. Is this correct for these studs? Does anybody know a source for the extra long stud required for the hole next to the starter? I have been working on this rebuild for 16 months and am ready to be finished already!
