Tom - try looking under the rear end, not the front. I'm pretty sure you'll see the unibody structure, as in this photo
; that's what I've seen, on Astros built after 2003, but of course I haven't seen yours. The front subframe is long, but just goes to the rear end of the transmission... or if you do have a full frame find out who did it and send him to my place - I could use a free custom fabricator.
The Chevrolet brochure for the Astro
when it was new has a reasonable exploded drawing
showing the front subframe, and no separate frame in the rear. Of course, Chevrolet could have radically redesigned the structure of van - without changing anything on the exterior - just before discontinuing the model, and other Astro owners didn't realize it... but I don't think so.
