HELP!!!

I WAS about 90% done with my T5 conversion when I ran into a major problem. While I was filling the trans I noticed some fluid buiding up on the tailshaft Looked closer to find the tailshaft housing is CRACKED Does any one know where I can get just the tailshaft housing for a 90 to 93 T5? Everywhere I've checked locally want to sell me a whole trans and I don't want to shell out all that money
