I just ordered a set off amazon. Ended up being around $50 shipped. Thanks I didn't think to look there. Jegs has the p/n but it says call service rep to order. The service rep told me it's a discontinued part.

I was starting to have flashbacks to a couple years ago when everybody had 1"+ torsion bars listed for like $150 and none in stock. I ended up spending big bucks for just suspension bars. Now they're on sale for around $150. Go figure.

Anyway, thanks everybody for all the help and hopefully this thread can help the next poor sucker with his replacement gasket problem.
