I am not positive this car will have it because it's automatic but it is apparently a turbo according to the VIN

Some of the 88's have a VLSD.  The Shiro's.  The one in your link looks like one.  Don't know if they all had the VLSD or if some had the CLSD.  Something to check.  The Hemmings article implies that they all do.  They have special axles so don't swap easily.

I have a vlsd out of a Shiro and a CLSD. You are correct. The swap is not a problem as long as you have the Shiro half shafts. They are very different on the differential end. I dont know how to verify on the Shiro or not. The wheels and the white paint look like it. The diff should have a small VLSD tag on one of the cover bolts

Too far away for me but someone might be closer that has an interest

The Shiro wheels are painted white, so unless they have been changed, then probably not a VLSD. These appear to be standard turbo alloy wheels. I'm wondering where all the turbo labeling went on the body. White repaint maybe?

All good questions. I don't remember there being an engine picture but the VIN indicates it should be a turbo. I am unsure if all the turbo cars got LSD's in that year range
