Now I know why 904 was having issues

bOb, I actually toyed with doing that. However, I was concerned that the aluminum mounting ears might snap off being on the end of such long levers (bolts), once all the weight of the internals was added. I'm guessing you didn't have any problems? Might have to revisit that option. Work height seems kinda low though.

no trouble at all. notice the od unit on the table in the background. that's the 518 I installed in my truck. weight isn't a concern. the thing I will do someday when I rebuild another 727 is weld up brackets so the trans is 90* to the stand. that will make it easier to work on and install the valve body.
