Need Weber help....and parts?
 

I was goign to put in some new emulsion tubes in the 40IDF only to discover that they are a hair too wide for the threaded pieces that hold them in place.

Anyone run into this issue? Anyone have some extras laying around we can test fit? YES...I'm talking about the the two brass bits that stick out the top and are slotted for a screw driver.
OLD emulsion...fit right in. NEW ones...too tight to fit.
