looking for a plain ol' diff cover...

need to replace the cover on the 8.25 diff I got from Pick N Pull as you know they knock a hole in them to drain the fluid out. Googled diff cover and looked in the obvious places (Randys, US Gear) and all I can find is the cast aluminum ones with the set screws and whatnot's. I just need a plain old everyday factory non-chromed replacement! Whew...
