I realize this is my first post in this forum, however I do have 25-30 Saiga conversions/restorations in shotgun and rifle of all calibers under my belt and half a century of gunsmithing
The spring your talking about is the dis-connector spring.
I always reinstall the BHO on all the Saiga jobs I have done. They came that way and after I go through all the restoration I put em back that way. You can purchase a unmodified ( modified means the hammer has had about .100 removed on the right side to clear the BHO) or you can buy one already modified that just drops in. Savings is miniscule compared to time and materials. Reuse your axis pins.
I prefer the plate over the Shepards Crook. But it is entirely up to you.
I just buy the kit(s) from Greg at Carolina Shooters as piecemeal parts and then having to modify those parts just is not worth the extra time IMHO.
Just take your time with basic tools and you will be fine. To thread a barrel/install a muzzle/move the FCG/Pistol Grip/Sand/Paint/Folding stock (whatever you choose) takes me about 3 hours with lots of breaks.

No problem brother. I just have to decide whether to do the trigger move or not. I personally like the way it is. That's why I bought the saiga. I never liked the ergonomics of a traditional AK. The trigger set back actually was better for me. I'm not a little guy. If one of the guys interested in the rifle really wants it, and will reimburse me for the $50, I'll do it. If he doesn't seem serious about buying it, I'll probably just keep it. In which case, I'll keep it the way it is. We'll have to see. Thanks again.... Mike....
I have a couple of old fart buddies that prefer the sporter configuration.
Guns, Cars and Women are a personal choice.
I know this subject is a little old, but Had to add my 2 cents worth. I've recently converted two Saiga rifles, and had no problems. I ordered the parts from CarolinaShootersSupply.com, it came with instructions, and I went to work. I also viewed an excellent video posted on youtube.com which covered the project nicely.
I didn't have to make any metal modifications to either of my guns, except to grind off the rivets which you replace with supplied pins. Otherwise, there was no other extra work, just stripping it down to the bare receiver and putting it back together with the new parts.
I used the G2 trigger group, moved it forward and absolutely love it! Unlike the old 2 stage trigger, it is a 1 stage trigger and is very smooth and nice.
Don't know if any of this helps, but since I've actually done it, I thought I'd write.
Right now I'm waiting on my magazine adapter for my .223 to use AR mags. That should be another fun project.
