Arisaka bolt parts.....

I visit the military collectors site frequently (looking for info on M1 carbines...) and noted that there's a board there just for Japanese rifles, etc. They also have a pretty large sale/WTB board as well, that you might want to look (if you haven't already done so...).]

You tried these guys?

Might be cheaper to just get a complete bolt, then take off what you need.

LoonWulf,
You can use Type 99 bolt knob and firing pin in a Type 38 bolt but both have to be installed as a pair. Vice versa does not work.

There is also a gunsmith on the West Coast who makes the reproduction safeties and firing pins for the arisakas T38 and T99 for less than $40 each last time that I checked, Numrich aka gpc corp was selling what I assume was this gunsmith's product at a higher price.

I bought a T99 repro firing pin from him about 6-7 years ago and it did require a degree of fitting to make it work with my bolt. You will need a firing pin protrusion gage or carefully measure the fp protrusion if you go this route.

Occasionally, you will see a good buy on a genuine safety knob on ebay (especially an altered or last ditch safety knob) but seldom a bargain on a firing pin. However, some of the safety knobs may be problematic and not engage properly.

What about E Bay?
