Does anyone here know of a place or vendor that sells a non cast aluminum oil pan for a 1999 V6 Vortec out of a GMC Jimmy?

I do not believe there is one available. The pan is actually intended to be a structural part to support the engine block.

It's just that I'm afraid of breaking the pan because it's going in a '57 Willys Wagon and that thing would not be fun to tow home. A non-cast pan would take a little bit more abuse than the cast one i have now. Or am I just off in stupid idea wonderland?
