[TR] TR4A trailing arms

The holes are not wonderful.  I am the one who did it.  Actually they ARE keenserts that I personally installed with the Patton kit.  

At the time I did not realize that the original holes were not well aligned in the "lugs". So the TA and the stud circle are not co-axial. This resulted in 1 or maybe 2 of the drilled holes for the keenserts having a small break-through in the inner wall of the TA.  

This was done 2 years ago, and probably 2000 miles ago with no obvious problem.  

BUT it has been nagging me and I feel that it is less than 100% perfect and the opening can allow water ingress and set up corrosion causing long term problems.  I did apply JB weld to the perforation to try to seal it but that is not really a "repair". I would really HATE for the hub to separate from the TA!!!!

So I think it is better to proactively work to make the TAs right

I will likely fit the Goodparts axles with 3/8" studs so the studs themselves currently in the replacement arms are not critical.  The aluminum of the trailing arms does need to be in good shape.
