i would think a ttb 44 spindle would be much smaller. Maybe a D50 spindle, but I doubt it. Redrilling them just perfect was an enormous PITA though. I think I am going to do it right, it is just going to cost me alot. $440 for the forged hubs and $320 for the forged spindles jus to get started. Still need, brake caliper brackets, calipers, rotors, bearins, flanges, u-joints, and 35spl outers.
A regular non forged, non Solid Axle hub and spindle will work, but it means I have to run Ford brakes, which means I need to find the stock Ford caliper brackets and then space them accordingly.
It is a general cluster****.
