Just remember, major offsets of the wheels or excessively thick spacers/wheel adapters will alter the scrub radius dimension, which an lead to potential handling issues.
On these old trucks with an S-10 frame, you won't fit a wheel with enough negative offset to negatively affect the handling that much. Mine handles like it's on rails. In fact, if you read up on scrub radius, moving the wheels out makes it easier to steer in parking lots.
The below link is an image of a truck that was very competitive in Goodguys Autocross (it now has a scout body on the same chassis, wheels included). I guess his handling wasn't negatively affected by those deep dish wheels.
47 Chevy Autocross TruckThis truck is also on an S-10 frame. The rear suspension was modified, but the front is S-10.
