A, B, C & D: show up occasionally on ebay.
E, F, H, & I: I've never seen these parts outside of a complete transmission. I've seen one example of an aftermarket outer lever (H or I) which was entirely different than the original, and would not work.
K: rumored to be available from Walcks
Most of these same parts were used on pickup, station wagon, & delivery vans (DJ series) up until 1960 or so.
*** Note - K vs k-1: Item k-1 is the remaining intact grommet/sleeve that came off my '46. K are NOS Willys parts which I found. I suspect that K was an assembly-line item and k-1 was a field repair part. K has the steel sleeve molded into the rubber, and it's very difficult to install by hand. k-1 is a softer rubber, and installs easily, with the steel sleeve inserted after the rubber grommet is installed.
*** Note - Taper Pins: I've been told that taper pins are an SAE and AN standard. They are available from machinery supply houses and aircraft hardware suppliers.
If you're looking to find some, the dimensions of my pins are:
- Length: 1.3 +/- .005"
- Max dia.: 0.158-0.160"
- Min dia.: 0.133-0.135"
