Ok so lets really talk K-members here Folks

BINGO!
Maybe the low cost solution to the front steer discussion should be about manufacturing proper steering arms for front steer applications that mate up (bolt on!) to the stock uprights.
If the steering arm places the tie rod end properly, minimal bumpsteer and correct Ackerman for ANY front steer end use is a matter of selecting a rack of the correct length to the inner pivots for the intended chassis, using the correct tie rod length, then precisely placing said steering components in the chassis by modifying the stock K frame or using an outright replacement.

sounds like you're on the right track.....please let me know when they are available
