These little beauties came from multiple locations last night. They look well made, and actually fit all the dimensions required. The additional plus is that they are treaded so you can completely remove the poly lock from the top of the adjuster. Sounds silly, but that feature could have been useful in knowing that the adjustment issue we were having on one cylinder was not caused by the poly lock. They're in now, so we will button up the intake after I address the connector less orange ground wire we found last night.
