22/45 Project Update

[LloydXmas250]

I asked a while back about accurizing my Ruger mk III 22/45. I ended up getting the Volquartsen trigger, MKIII target sear, and MkIII bushing. I got the trigger in fine but I'm having trouble with the sear. The spring is a completely different shape than the old spring and I'm not really finding anything helping me to install it. Also the bushing; does odd shaped piece that fits on the hammer come off completely and then just gets replaced by the bushing? I'm a little confused on this one. If anyone knows any guides or can share their experience I'd appreciate. Thanks for everything and Merry Christmas.
