Alan,
I think you can buy a kit including the fulcrum pins and tubes from places
like Ron Hopkinson in England. Or you can ship your old A-arms off to
Apple Hydraulic in NY and get them rebuilt, which seems to me like the way
to go. I believe that some replacement kits use threads different from
the original, so if you try to do it youself get the new fulcrum pins
before you start trying to make tubes.
