It sounds like more work then it is... Think about it.. The receiver is the exact same as any other ak47. Just the trigger is moved back an you dont directly release the hammer when squeezing the trigger.. The rivets holding the trigger get drilled out and moved to where the 2 push rivets are on the reciver. No drilling new holes or puting in new pop rivets..
There are a few videos on YouTube how to do it thats how I figured it out.. The ones I think are the best were done by 2 yougher guys.. Very clear on directions and you can see everything they do.. Just follow along and it really will be easy..
Oh and your better off just getting the kit as a whole... Much easier than pricing everything by itself..
And once again I stand by my new hammer spring I got from Carolina shooters... The thing is absolutely amazing compared to the old twisted one.
