Clutch Slave

I discover I have two different slave cylinders for my 1971 Sprite
(box of bits car)
One is 1" diameter and the hose connection is straight;
the other is 15/16" diameter and the hose connection comes off the
main body at a slight angle, maybe 25 degrees.  Otherwiise they appear
identical.

Anyone know which is the correct one?
