which i find funny, because everytime i have sent a power steering hose over there to be made....they couldnt do it, and i had one made the same day, using fittings i get at NAPA...
on a side note, i made several from 15 bucks worth of parts from home depot. that link chad gave is what i based mine on.
as for the ball bearing, if you cant find one, go to the "chick jewelry store" across from spencers in the mall....get a pack of their ball stud earrings. they work great! cut the stud a little stud off and use that as a locator in the spring (which a BIC pen works great for)
