Hi Dave, there three alignment pins required, flywheel locking pin 23-020 camshaft locking pin 21-123 and injection pump locking pin 23-019 or 23-029, these are the Ford part numbers but in most cases you can get by, by using suitable bolt of the same size and lenght, or on the inj pump I think its a 6mm drill bit.
