3-speed shift lever grommet available?
Mr. Townsend, you are absolutely correct. I finally received the 3467791 and it was indeed a hard plastic part. So it could not be a supersede to 1941699.
Took your advice and look over McMaster-Carr online catalog. Was unable to find an of-the-shelf grommet that met the dimensions that matched 1941699. Those dimensions are: 1/2" id, 3/4" hole size, 1" od with a 1/4" groove.
Final update on how the split grommet worked. It didn't at first. When put the two halves into the shift lever and place the shift rod into the the grommet with the brass bushing, the grommet immediate fell apart.
After contemplating the issue, I found a thin washer that was a bit too small to fit on the shifter rod shaft that the brass bush fits on. After a bit of filing with a rat tail file I got the washer to fit very snug on the shaft. Once the washer fit, it slid up to the small shoulder of the shaft the brass bushing fits on.
The split grommet was held together between the added washer and the cotter pin on the other side. rather then the sloppy shifts the linkage use to make, now it has very short positive motion with the shift lever in the car. Very happy with the results!
