Hi, I am replacing the cables and housing for both the brakes and derailers on my 84 Trek 510. Please bear with me its my first time. My cables and housing hasn't come yet so I have not attempted it yet. My question is: the derailers require no housing except the rear derailer loop right? Can I use the same housing I bought for the brake cables for that loop? http://www.niagaracycle.com/product_...oducts_id=2241

Also am I going to need any ferrules? What size for the housing I bought? Where exactly will I need these? Just inserting the cable into the loop and out into the derailer or will the brakes require any of these?

Thanks for any help you can give!
