This is how how I did my Renix TPS to HO Throttle Body.
Items Needed
a. (3) solid aluminum spacers from Homedepot. #10x5/16"x1" One connects to the throttle shaft and to for screw spacers. 3 at 80 cents a piece.
b. (1) 1/8 x1-/1/4 Tension pin. This is to replace wiper arms from Renix TB. 90 cents for 2.
c. Hard plastic bushing. .8 in x .68in. The main thing is that the aluminum spacers fits in it snug. It can be grinded or cut to length. They are available from ACE hardware but I didn't need them. I had some plastic cart bearings that I used.
d. Two 1-1/2 inch screws with hex heads #43103Q. 90 cents a piece.
1. Wallow out the inside edges of the screw holes on the Renix TPS. The holes on the HO throttle body are slightly closer together.
2. Cut bushing down to approximately 5/8 in.
3. Dremel out one of the aluminum spacers to fit the shaft on the throttle shaft.
4. Insert the aluminum piece into the plastic bushing.
5. Place on shaft of TB mark and cut off excess.
6. Put a small amount of epoxy on both pieces and put on TB shaft. Measure distance from TB to TPS and trim aluminum spacers.
7. Put all together. Use a 12 volt power supply and then hook-up multimeter like shown.
8. Move arm on TPS until you have the correct voltage for engine at idle. I went with .71 volts for wiggle room later after. It should be .75volts. Mark the TB and the black bushing. The mark on TB is for reference later after you put on new wiper on TB shaft. The mark on bushing is where you are going to drill for tension pin.
9. Drill hole for tension pin all they way through just past the inside of aluminum spacer. Use drill bit slightly smaller than the tension pin.
10. Tap in the tension pin.
11. Put the assembly back together and hook the multimeter back up.
12. Adjust as needed. That should be it.
