It is not the Power Glide starter that has a different nose, it is the truck Hydramatic.
1938-62 216, 235, and 261 starters will all bolt up the same(except Hydramatic). They will need to match the 6 or 12 volt flywheel though.
On your 59 you would need a 1960-62 truck starter or a 1955-62 pass starter.
