DanM Posted August 5, 2022 Share Posted August 5, 2022 (edited) Hey All, I need to source a replacement 7/16 UNF x 8 inch long double threaded stud for my Westfield Miata - It is to connect my rear Knuckle to the lower control arm. Does anyone know where to get one? or have one made? Its to replace this one that I had to cut in half to remove it. Thanks.

fastg Posted August 5, 2022 Share Posted August 5, 2022 (edited) If your replacing the rod, if you replace the nuts then the thread size becomes irrelevant. So checkout me favorite shop https://www.mcmaster.com/threaded-rods/threading~threaded-on-both-ends/connecting-rods-5/system-of-measurement~inch/ Thinking about that, why it it an imperial thread, coming from a Miata or Westfield?

DanM Posted August 5, 2022 Author Share Posted August 5, 2022 I know, intriguing isn't it! lol The whole vehicle is a mixed batch of metric and imperial. All the miata bolted stuff is typically metric, but because the westfields use parts from older UK cars (Bushings etc.) there is also a lot of imperial stuff too!

fastg Posted August 5, 2022 Share Posted August 5, 2022 How old is the stuff there using, the UK went metric while I was in high school, so the 70's! Graham Link to comment Share on other sites More sharing options...
DanM Posted August 5, 2022 Author Share Posted August 5, 2022 Control Arm Bushings are from a Hillman/Chrysler Avenger!! Link to comment Share on other sites More sharing options...
fastg Posted August 5, 2022 Share Posted August 5, 2022 Hillman Avenger, nasty, but at least it has donated a part to a much more interesting vehicle:) Graham Link to comment Share on other sites More sharing options...

DanM Posted August 6, 2022 Author Share Posted August 6, 2022 So after a lot of thought, input from the UK forum forum and price comparing ($USD -> $CAD +Tax + Shipping) I decided to go with 2 new grade 8 bolts from McMaster-Carr. https://www.mcmaster.com/91257a487/ Fingers crossed it will do the job!
