victim - 1981 Datsun 720 starter bolt and stud

Postby [email protected] » Sun Feb 21, 2016 11:13 am

I am fixing up a 720 for my grandson to drive. I have only had this 720 for a few weeks and it is obvious the previous owner should not have been permitted to have or own tools. The new starter was barely ( and I mean barely) bolted in. With 2 bolts. I believe the 720 should have a bolt and a stud ( on top ). The question is what thread pitch. I know they are 10mm but are they 1.25 or 1.50 pitch.
The previous owner used 1.25, however when I attempt to use 1.25 they thread in easy about 3 turns and bind...if i attempt 1.50 they bind at about 4 turns. What is the original thread pitch?
