Offset for 88-98 Chevy truck...?

What offset should you run on a Chevy 88-98 standard cab stepside bagged and wanting to run 22x9.5s...? Wants a set of Martin Bros. wheels, but not sure what offset to order them in to tuck...

My Suburban is just static dropped 5/8 and I am running 22x9.5 with a +16 offset and they barely clear in the front with the fender lips rolled. If it was bagged I would want it just a little farther in, maybe a +20 or +22.

I forgot that I also have Belltech spindles. They push the wheels out 1/2 inch so if you are running DJM spindles it might make a huge difference.

I had 22x10 with 7" bs and 3' lip bagged on a 93 truck
