Again with the thinking instead of checking. I've made this incredibly harder than it needed to be. Thanks to Swordy I checked at the Auto Zone right around the corner from me and they can have me a set of rebuilds next day for $300. I even get $100 back on core charges which should pay for the install since I'll probably wuss (sp?) out and get the front end shop to do it (too many other projects ongoing: deck, landscape, plumbing ...).
BTW, you can also order online at www.autozone.com
