Gary,
I used a Maverick ET-73 for quite some time as well as a Digi-Q DX. I installed two Guru eyelets and could get the two Maverick probes thru one eyelet and the two Guru probes thru the other.
I picked up an ET-732 only to find out that neither of the probes would go thru the eyelet. There is a much wider crimp on the probe tips where they join the probe leads making it impossible to pass thru. I called Guru and they said they would investigate and possible modify the diameter of their eyelets. I may be mistaken, but I think Cajun Bandit is offering a new eyelet to address this issue.
I ended up using a threaded lamp repair shaft from Lowes. I can pass all four of my probes thru that one opening which makes for a neater fit by keeping all probes leads together.
