Yes, your truck is the same as our 1986-93 trucks.
You should be able to run drop spindles, but they will push your wheels out to a slightly wider track. About an inch( not sure of the centimeter equivalent...4.5 to 6...I guess ). They will also cause more clearance issues with your 16X8" wheels.
If you are just going for a static drop, you can re key the torsions,flip your lower ball joints, or use drop control arms. The latter however complicate air ride installs.
I see what you are saying about the quarter windows, and your mirror placement is farther back on the door. You also have different bed sides....sometimes called japanese bed sides around my part of the country.
Truck looks good though, and good luck with it.
