I Have spent approximately 9 hours going through every thread on this forum, Pelican and Rennlist to no avail to find a thread on how to rekey early locks

its for door locks on a 1967 911, lots of threads show how to do the brass type "D" shaped wafers and Tony Eugenio is the man but my lock has pins and springs that don't just fall or pull out

and i have no idea how to remove them, if in fact they can be removed for fettling for rekeying

any help would b greatly appreciated.
