I received the new headlight switch knob and shift lever knob from Rudy today. Already got them installed.
I know there was some discussion regarding the difficulty involved when installing the shift lever knob on, not only the Henry J, but on the other post 1950 Kaisers with manual transmissions that have press-on shift lever knobs.
On a previous thread, which I Jaked up to look at, in addition to my suggesting lubing the shaft with Go-jo, Joe Frazer recommended putting the knob in hot water to soften it. I tried both of those methods and got it about 3/4 of the way on and it would not go any farther no matter how hard I pounded with the rubber mallet. I then went in and grabbed my hand held blow dryer and heated it all around evenly for quite awhile. Then I was able to drive it the rest of the way on with the rubber mallet. Even after this, it still took some pretty aggressive whacks to drive it all the way on. Rest assured, it won't come off!
That leads me to how to remove the original one. I just cut into it with a hacksaw till I felt it hit metal then stopped. I then used a side cutters and a hacksaw to gently remove the remains.
The headlight switch knob was a piece of cake as always. The previous owner had purchased a choke knob from Rudy and I installed that back in March so now I have nice looking knobs in the car. Good fortune was also with me this week when I found very nice overdrive cable with a dang near perfect knob on it on ebay. I don't have the ambition to replace that today but when I do, it will be a big improvement over the knicked up one that's in it now.
Progress is being made!
