Ok, since nobody came up with a workable solution for me to get the original part numbers, I had very many problems to find the right parts at R***A*to.
I think I'm almost there, maybe someone can help me for the following?
I need the correct tie rod end adjusting sleeve (from the pitman arm to the inner left drag link according to RA terminology)
spec's as far as I could find: length 5,5", the link and tie rod end have a 1-18tpi clockwise tread.
That is for a '89 F-350 4WD chassis cab front axle OVER 4200#
(ford uses two of those sleeves on this set up, one clockwise, and one counterclockwise)
But due to the fact that RA is very inconsistent with the technical details (horribly bad!!! I couldn't find the right one.)
So, if someone knows which one I need, I can order my parts, they still need long enough for the trip to Europe.
Thanks.
