Is there any GM truck that has a front-end similar to the Chevy Astro/GMC Safari?

I'm looking at getting a grille guard for my 97' Chevy Astro van, and, since there doesn't appear to be anyone who sells guards specifically for the astro, I was wondering if the van's front end was similar to any truck models. I had heard that the Astro/Safari was built somewhat based off of a truck design, and I was wondering if this was true.
