help identifying the year of my transfer case (50D)
So i finally got around to attempting to scrub 27 years of carbon buildup off the undercarriage of my '88 ROW D90 2.5TD. I'm also pulling the serial numbers to submit to the british motoring museum to get a heritage certificate. In doing so, it may be just me, but my gearbox looks newer than the rest of my components. the serial number indicates that it's a 50D. Can anyone confirm that this is the correct original box for my variant? Cheers!
EDIT: Gearbox not transfer case. OOPS
