Interested in this as well. As far as I know, the iron-tops had the forward shifter position, and were only used in the squarebody's. The aluminum-tops had the rearward shifter position, which was the same as the nv4500 that replaced it, and came in the gmt400's. I've never heard of a forward-shift-position with an aluminum top.

I've personally never seen an aluminum-top, so I can't comment on the specific differences in the shifter.
