Wells vTPS install
Below is my install of a Wells tps210, There are a few steps in the begining and middle that I missed taking photos of but you should be able to fill in the gaps
This is the sensor that I used
I started by removing the stock tps sensor and removing everything to get it to the bare plate, the two items that I kept were the actual plate and then the yellow plastic piece that fit on the throttle body shaft (dont have a picture of that)
You will see I removed the metal spacer as well, this was done by flipping it upside down and giving it a good hit with a hammer over an open vise
Next I marked on the backer plate and the Wells TPS sensor the direction of motion
You will see in the photo of above I already have the yellow plastic piece insterted into the Wells TPS, what I did was cut it down to just the upper half of the piece, then take a file and file away grooves for the Wells TPS to slide into. These are the files I used
Next I took apart the Wells TPS plug
Then mounted the Wells TPS to the stock miata backing plate. To do this I installed both back on the throttle body and found my alignment, marked it and then removed them both. Clamped the Wells TPS to the plate and drilled two holes and bolted the TPS to the plate
Then soldered the Wells TPS wires to the stock connector
Next was to reinstall the stock cover, because of the mounting position of my sensor I needed to remove the back corner of the case to get it to fit
And then install it in the car

Does it work properly like that, with the D-shaft off center?
When I installed mine, I had it off center as well and it put noticeable stress on the tps. With the mounting screws a bit loose, I saw it move as I turned the throttle. Didn't feel right so I binned it and bought the correct tps with D-shaft hole. YMMV of course.

You may be right (and maybe I misunderstand what your concern is), but here's how I see it (bear with me as I somewhat state the obvious):
The throttle only rotates 90 degrees. Therefore, it would stand to reason that the TPS would only rotate 90 degrees as well. So it would seem to me that you need to identify the 0 degree (closed) and 90 degree (open) position on both the throttle and the TPS and align them accordingly. Then the yellow plastic piece can be inserted relative to that collective orientation and should lock the two in place.
Wouldn't that eliminate the possibility of undue mechanical stresses being put on the TPS?

I'm using the Wabash. I just slid it on the D-shaft, marked the 2 holes and it was perfectly aligned.
