Origional post-----------------------------------------------------------------------------

The engine/tranny is a b18c R with about 40K miles, but its grinding already so who cares about miles. Well, my 5th gear grinds while shifting into it so I'm guessing its a syncro: (links below if you care)

So now I'm trying to buy all the parts I need to replace the 5th gear syncro and I guess 3rd as well since that one is supposed to fail a lot.

My question is, what parts do I need exactly?

Where can I buy the parts for a good price? part numbers help.

Basicly, a friend who is very good with tranny work will be doing the work and I'll be helping as I have changed clutches before, but never internal tranny work. So I have to buy all the replacement parts that will be needed.

Therefore if there are packages that I can buy that includes the replacement parts, that helps as well.

Update 1-----------------------------------------------------------------------------------
I saw that Gear Speed Transmissions has these:

1st thru 5th synchro set (1-piece 2nd gear) $215 shipped

What do I need? And is that all I need parts wise. I know we'll need a lot of tools for the job, but I have to make sure I have all the parts.
