Very sexy 8m there Joe...love the stock.
Be aware when searching for a blade bayonet, if anyone selling states that it is an early type, straight eared collar, that won't work for you. Those would be Russian anyway...but are commonly listed without nationality. Yours uses an angled ear collar, which is far more common...but the Canadians are parting out Russians like mad, so the early ones are turning up more than usual. If you find a pretty early one for a good price...get it...any spike bayonet handle will work, but will cost you a little more time and money...usually less than ten bucks.
Also, if searching eBay...aside from the 'hunting' section it usually will divert you to when searching for SKS anything...check both the Antiques and the Collectibles sections. They get less traffic and often you can find some deals there...along with some wingnuts with delusions of grandeur...but I have had some pretty good bayo luck in those sections.
