Hi, I ordered a drag link repair kit. I did try to installed it without success.
I had two problems.

First one is the screw are not the same.
The lenght of the thread is longer on the new one and the depth of the slot for the cutter pin are shorter.
I was not able to screw them enough to get the cutter pin goes through.

Here is pictures of the repro versus the original side by side.

I end up the put back the original.

Also, the plate that keep the rubber seal in place is a very thin metal plate. I kept my old one since it was harder and had some spring in it. Also, I think they are made in stainless.

Does anyone has some feedbacks?

Pascal,
I had a similar issue with the reproduction set I bought from Walcks.  I couldn't get them to thread in enough to use the cotter pin.  I found that the threads were buggered up.  I cleaned the threads up with a small file and was able to insert them in far enough to lock them in place with the cotter pin.  But...it still bothered me enough to just use the originals.
