The Stovebolt Site Forums The Shop Area Engine Shop Trans cross members?

I've got a 51'GMC 3/4 Ton with a chevy 235 and a saginaw 4 speed.Rear cross member is missing.I havn't driven this truck yet but the more I think about it, this can't be good.It's an older conversion 70's?/80's? I don't know,But I don't like the idea of the trans hanging off the bell housing with out support to the rear.Is this the way this is,or am I missing somthing. thanks Jimmy
