It would require some tweaking on spindle but,  if you draw a line thru pivot points on the frame, measure how far in the pivot on tie rod at rack is say 2".  Then the tie rod should mount the same say 2" from a line drawn thru the mounts on spindle.  Yours is not even, its a tad higher on spindle, so raising the rack to make the arms and tie rod parallel.  Now if the mounts on frame top and bottom are not same a spindle top to bottom then use a %.  If you mount up 65% of on frame same on spindle %% wise.  This should get you real close.

He HAS to have a correct rack adapter FIRST.

Yes he will need a rack adapter first to get the pivots in line with the top and bottom pivots.  He will need to get his steering arms parallel with his top a arms to.

and bingo is your name-o!  That is exactily what I had in mind!  The front suspension are to the prints, but there is always for improvment....The distance between the top and bottom heims on the uprights are about 1" further apart than the upper and lower piviots on the frame..as seen in the pictures....did that make any scense???HAHA

Even with rack adapter to put in line with frame mounts.  The spindle tie rod mount is outside the the line from top and bottom spindle mounts. Move the rack pivot out to be inline with frame, the tires will bow out under compression because of where its mounted on spindle.

Look closer Carl. If he made the uprights to plans,and he says he did, they are in line. I enlarged the pic and it appears to me to be correct. Smaller pics made me have to look very closely.Enlarged it is more apparent.

Actually, I just went to the man cave, and pulled tape on the uprights....the steering bolt is .500 further out than the upper and lower heims center line...hmmmmm, and the plot thickens.  Those uprights came from Kludge....

here's mine. It's not a big deal. I have less than 1/4" toe change in 24" travel. The inners are much more important. Rack position is critical and 1/16" change in position can make dramatic changes. Take your time! measure and measure and measure......................

Make your rack adapter like rorty drew it and you'll be fine.

The steering mounts are further out on the spindles to provide Ackerman....

Everybody is making good points.  Carl is correct that the tie rod should be close to parallel to the arms.  And master is right that you will need that adapter to make the rack mounting points wider.  Actually I think that you will find that the best width for the adapter on the rack is wider than a line drawn from the top arm mount to the lower arm mount.   It needs to be wider because the mount on the spindle is "further out" than the outer a-arm mounts.

ETA:  Based on the picture I think that Fabr is right.  If the rack mounts are wider then the tie rods will get shorter and become parallel to the arms.

The thing that screws up the tie rod needing to be parallel to the A-arm is camber change because with camber change the two A-arms are not parallel to each other.  So then you revert to Carls plan of the same percentage up for the rack as for the tie rod mount on the spindle for a happy medium.
