Crank pulley bolt
Can someone provide the crankshaft pulley bolt size for a 1970 307? Pulled mine few weeks ago while working on pulleys and now can't locate it. Thanks in advance.

Re: Crank pulley bolt
7/16 fine thread for the center one. 3/8 for the three smaller ones around it.

Re: Crank pulley bolt
If you misplaced your washer too, I have an extra I can mail you. They're pretty stout.

Re: Crank pulley bolt
Thanks LSU. I've still got the washer. Pulled the original bolt because I needed a longer one (had to shim pulleys) and I think the darn thing fell under the seat of my daily driver although I can't see it.
