RE: [DML] Re: Grady's, HRC Angle drive

Mike,

Point well taken as the speedometer system is only as strong as its weakest
link. The angle drive gets blamed for many failures caused by problems
upstream in the rest of the system. Everyone with a VIN # before #005179
should consider upgrading to the shorter (26" verses 36" before this VIN #)
cable (Part #111412G) and the revised support bracket (#110528) used on
later cars. The shorter cable goes straight to the wheel instead of looping
over to the A.C. hose like the earlier cars. The bracket gives the cable a
straighter route to the angle drive as well as more support at the wheel.
This is a must if you want the angle drive to last longer. Decreasing the
load or drag even more would help also. Years ago someone offered a one
piece cable to eliminate the Lambda counter. Being a purist I didn't like
the idea at the time but if you follow factory directions on oxygen sensor
replacement then the counter is redundant and could be eliminated. If there
is interest I could have these cables made again. There is also a
weather-proofing kit that used to be available which kept water and debris
from entering the angle drive which helped prolong its life.  It consisted
of a molded boot, a machined axle nut, and misc. o-rings. Recently I came
across about a dozen of these kits (#113263) and have put them on the
website (No picture as of yet so just type in the #). I could make this
weatherproof kit again if there's enough interest.

We really need to look at the speedo drive mechanism from a
system perspective.  Focusing on the angle drive alone isn't 
enough.
