20/25 Hypoid Rear Axle.

We find the Perfect seals on the half shafts on this axle run too loosely on the shaft. On both SpectreCodename for Phantom III and Bentley we run seals one size tighter than the correct size and get good results. Will you therefore please alter the seal on the 20/25 L.O.P. from 20012 to 20018.
