Those two are your savage guys for sure. But a bolt lift kit, bolt handle, polishing of parts (cocking pin, cocking cam, ejection ramp), replacement of the sear spring, and even bolt head and bolt body, are all pretty much do-it-yourself type jobs. "timing and truing" it's a term referred to about savages that's a little up for debate as far as return on investment goes. It basically has to do with ensuring that the cocking pin, sear, cocking cam, and ejector ramp are all working in unison to ensure smooth operation. Personally, I've never had a savage action timed n trued, but I've read mixed reviews on the ones that Fred had done. Some say they got charged $150 to basically have a few spots polished on their bolt.
My suggestion is to try the do-it-yourself stuff and see if it satisfies your needs as far as the action is concerned. Then you can either buy an aftermarket bolt knob, or send yours to someone like Phoenix custom rifles. They offer some pretty cool knobs for savages. They also do rebarreling jobs on savages, but they do away with the barrel nut, which looks cleaner, IMO.
They have my savage right now. I'll let you know in a month or so how it went...
