For your purposes...Steering head angle and "Rake" would be seen as the same, but that's not all there is to it...Search for "Rake and Trail" if interested.
Really all the Neck Rakes listed above are accurate. The FXDX, FXDXT, and FXDS have a 28° neck and 0°Trees
BTW, the online parts sites usually list the steering head angle as part of the frame description
if neck angle is the same and they both use the same wheels size and the same trees would not the rake and trail be the same?

It's interesting that they list rake with the frame like this... I was always under the impression that when rake is listed on a spec sheet for any given bike, it is the rake as measured when the whole bike is sitting on level ground, as opposed to the angle of the steering head in relation to the rest of the frame. I thought the same frame could be used on different bikes and yield different rake if the height of either wheel is different, or the height of the rear shocks, or the length of the fork tubes... But maybe I'm totally wrong!

I speculate that a Frame is built with keeping the neck at the same angle on a produced model (within reason)
You always have to have a reference...how could you make a frame without some reference.
But then there's the Bigger picture of Overall Rake and Trail.
if neck angle is the same and they both use the same wheels size and the same trees would not the rake and trail be the same?
If both bikes are at the identical height...Yes
Raise the bike equally front and rear (eg. shocks,forks,overall diameter of Whl/Tire Assys)...Same Rake & Increased Trail Lower the bike equally front and rear (eg. shocks,forks,overall diameter of Whl/Tire Assys)...Same Rake & Decreased Trail
Raise the Front only (longer forks, Bigger overall diameter Whl/Tire Assy)...Increased Overall Rake & Increased Trail Lower the Rear only (shorter shocks, Smaller overall diameter Whl/Tire Assy)...Increased Overall Rake & Increased Trail
Lower the Front only (shorter forks, Smaller overall diameter Whl/Tire Assy)...Decreased Overall Rake & Decreased Trail Raise the Rear only (longer shocks, Bigger overall diameter Whl/Tire Assy)...Decreased Overall Rake & Decreased Trail
Btw, Raked Trees have the Opposite effect...Increased Tree Rake = Decreased Trail...and vice versa .

I always thought the FXDX and FXDS had 28° up until at least 2006 (I know my '94 FXDS is 28°)
If I remember correctly, the FXDL is 32° and the FXDWG is 34°
There are errors and inconsistencies even within HD current Sales Brochure and web presentations and then 3rd party sites subsequent presentations that use HD provided info. One can see (and follow) how HD arrived at these errors and typos. The Part Listing are a pretty good source for correct information because you can cross reference the information to validate.
That being said...
2005-Earlier (Neck Rake Only):
FXDL / FXDWG same 32°
Other FXD models 28°
2006-later (Neck Rake Only):
FXDWG 34°
Other FXD models 29° (even though you can find an explainable discrepancy in the "Sales" info, but no discrepancy in the parts listing)
thanks that is what I was looking for... Im really only interested in the frame and want it the same dimensions as the FXDX. Im doing different wheels, tires, etc
just wanting to make sure im starting with the right bones
thanks!
