stepper motor thread size

[spitfire4v8]

Does anyone happen to know the stepper motor thread size? I need to buy a blanking plug and don't have a stepper motor to hand to size it up. cheers.

Hi,not sure what you are trying to do maybe like me new ecu with repositioned idle valve,but I too blocked the original stepper hole off with a plug,do check it has sealed by blowing down the rubber pipe connected back to the plenum throat as although my plug had bottomed "no laughing at the back" there was still air leakage thro the housing and would have caused chaos if I had tried to run it like that.

Easier to stick a core plug into the rear of the plenum and install a tapped barb for the FPR doing away with the stepper housing too
