Is the bolt spacing wider or narrower on the steering arm compared to the strut. Is the late 120Y strut the one with the PBR brakes or the Japanese style. You should be able to use the standard 1200 steering arms with the PBR style stuts, this was my favourite conversion for my old 1200's. If the bolt spacing on the steering arm is wider than the struts, you 'should' be able to use Stanza or Sunny struts.

Is there anyway you can post up photos of the struts & steering arms? & where abouts are you. There might be somebody just around the corner who can help. I live in Sydney, David (ddgonzal) is in the States. dfj280 is in Sydney as well. Please fill in the location part of your profile.
