yikes sorry to hear of your troubles...
You can buy seal kits but they arent cheap! fastwrx.com has them for ~US$80 for a pair. Suby Aus should have them too.
Are you planning on replacing the joining bolts, apparently they are stretch bolts and supposed to be one use only. Although I have heard of people re-using them without problems. If you do replace them I'ld be interested to know where you get them from.
