DERLIN WAS: Delrin or Poly bushings? Worth it?

[SuffolkD at aol.com]

Someone mentioned to me that the A frame arms didn't hold up to the stronger 
bushings.  He mentioned "seam welding " the A arms so they didn't break or 
crack?

It may be for the heavier 80/90 series, but I though it pertained to the 
4000Q too.
Consider it urban legend until I get a confirmation.
I have the Blau ones in a bag, Never used........somewhere.

find ride quality to be bad. But i use poly now......
