12212156 is supposed to be universal, but before I screw anything up does anyone happen to have a 2002 Chevy Astro AWD with 4l60e bin? I'm fairly confident I can just use whatever 12212156 that is close and simply copy over everything but I'd really like to start out with a known astro/safari bin if at all possible. I'll straight up paypal someone $5 if that is allowed.
