Interesting differences in the two set ups - The old "G" suffix has 13mm bolts with washers all around, a smaller magnet drain bolt & unusual mounts, while the "H" has 10mm wide base bolts, thinner linkage rods & a larger 1/2" insert style magnet drain plug. Here are some comparison pics -
A little background on the replacement - It was purchased along with a 200tdi shortly after I got my 110, but the set had cut hoses & wires, bent pulley, missing parts & I didn't trust anything that showed up in the crate from the UK (looked like it all sat in a field for years). Pressure washed & let it sit while I looked for another complete set, so while it looks good from the outside, it is in unknown condition inside. UD sold me the current complete set up that I have been running. If I were a "real" mechanic I would open it all up & inspect, but instead, plan on putting in new fluids, driving it & flushing any crud out.
