Threaded rod and oil seals

I was wondering if anyone knows where I can get the 8x1.25mm threaded rod to make the tensioner tool, because I've been to a farmer supply place and home depot and lowes and all they have is that standard crap and they can't tell me shit about where to find it. I'd prefer it to be a physical location rather than an internet vendor but either way will work.

Also, what is the best way to remove the front and rear main seal? If I wanted to use a screwdriver I wouldn't ask this question...

www.gotbolts.com It's nice having them here. As well as House of Hose. Got my 3foot oil feed line for my autometer oil pressure sending unit w/ fittings for $10.
