KJW Co2 mag help

[novioman]

Dropped my KJW Co2 mag, straight down on to the feed lips, smashed to pieces.?

Found a place selling replacement feed lips. ?

Found all the parts on the floor luckily, even this tiny spring. Not 100% sure where it goes, but it seems to fit as I photographed here. 
Is this correct place for the spring can anyone tell me.

 

Thanks in advance

Probably the spring that acts against the slide lockback lever

Just found an exploded diagram, looks like I’am missing part 83 the follower lever.

So I’am wondering if the mag will still feed bb’s o.k and just not lock back on empty.

 

 

UPDATE,

Found it on the floor, lucky I didn’t hoover today.?

Hope this is right, fiddly to get the spring back in.
