back to my original question:

would it be possible to modify a d44 knuckles to kingpin style using stock toyota or d60 (or any other kingpin knuckles?) hardware?


Sure, anything is possible. Either look for an existing king pin D44 (as noted above), see if there are kits available (search with Google or other web search engine). If not, design your own kit, assuming you have a milling machine and tooling, should be no problem knocking one out <img src="/forums/images/graemlins/smile.gif" alt="" /> If you've got to pay a machinist to do the work, you may find the existing solutions are quite reasonable priced. Maybe call up Currie Enterprises and see what they have to offer.
