I would go to the local A/C hose shop as they should be able to make you up
replacments for about a quarter of what the dealer wants (maybe less).  I
always recommend this when folks call about A/C hoses.  Some NAPAs even have
machine shops that make up A/C lines and I have found my local guys to be
really helpful in this area.
