This is where the TPS will mount on the throttle body. Measure the mounting hole center to center distance and the diameter of the TPS center hole.

Initially I had thought the TSP would just mount up to the throttle body, but alas things aft gang agley. Turns out not only did the TPS I semi randomly picked to use needed a spacer but it also need to be rotated from vertical in order to have both full throttle and TPS movement. When I say I semi randomly picked the TPS what I mean is the throttle body vendor was of zero help in figuring it out. I knew I needed one with an 8mm D hole to fit the shaft and 32mm spacing to fit the mounting holes, I got that from measuring. So I googled till I found something that looked like it would work, with the rotated mounting holes it almost does.

The vertical holes on the adapter were drawn out using measurements taken off the throttle body. The offset holes were determined by putting the TPS on the shaft and moving it to a place where both it and the throttle had full movement, the adapter was then market and drilled. Once that was done I bolted up the TPS sensor and found that it would slightly bind on return and would sometimes keep the throttle slightly open. A washer on each of the TPS to adapter bolts fixed that. I had to use button head screws to mount the adapter to the throttle body so it would clear the TPS sensor.

Here is a shot of the TPS on the adapter, I don't have the nuts and washers on it here, but it's mounted up properly now with full travel and no binding.
