that one, my pedigree chum, looks like a 2wd turbo.
ALTHO it could be a 4wd raer end with a 2wd core and compressor.
what do the numbers say on the ID plate?

could be a 2wd turbo dude, they are the same as 4wd but the compressor housing moved as the mainfolds are different
altho they LOOK the same, 2wd turbo has a .50 trim compressor with a .42 comp cover, and a 4wd has a .60 trim compressor with a .42 cover - overspeed city with a 4wd cover on a 2wd compressor - i know, i've done it

generally speaking, 4wd turbo's have the actuator mounting arm bolted to the front of the turbocharger instead of one of the claming plates like on a 2wd.
