Here I go again, more tranmission parts needed

[odog]

For some reason my 420 trans is is leaking 80/90 out the front. I got home this evening and smelled gear oil, crawled under and found that the clutch and front of the trans is wet with 80/90. Im guessing the seal is leaking around the input shaft, or maybe that cover is broke?? When I put it all together, I didnt think I over tightened the bolts on the front cover, but maybe I did. If it is broken, is the front cover off a 465 the same as on a 420? If not does anybody have one they want to get rid of? I dont want to pull this trans again unless I have everything there that will take care of the problem. If its just a seal no big deal, but if the cover is broken, I want to have it on hand so I can put it all together.
