Three Saturdays ago when I tried to back into a space at Cars & Coffee my shift lever popped off. Disconnected at the base, stranding me 15 feet from my destination. Luckily it was in neutral. I dragooned a couple of bystanders to push the Spyder into the slot.
I quickly found it wasn't broken. Just disassembled. The lever screws into a socket near the floor of the shift housing, and somehow it had backed out. A few minutes later I'd turned it back into place with some borrowed pliers (thanks to this kindly UniMog-with-grenade-launcher owner).
And I was happy, because I now understood why my reverse lock-out feature had been getting funky.
The stock Brandwood shift lever is a complicated thing. Really it's two levers, one nested inside the other, so the outer one can be pushed down to allow the lock-out nub to dip below a gate to get reverse gear. As the inner shaft unscrewed it made the whole thing slightly taller—too tall to allow the outer shaft to be pushed down far enough unless I opened up room above it by backing the knob off a turn or two.
I had cut and welded on that box several times during the build in an effort to make it more compact and Spyder-like, yet never took it apart to see how it worked. Now, seeing how it went together, I also realized how easy it would be to replace with a longer stick.
One of the silly things I added to the box was a reverse lockout lever, the similar to the originals. Turns out it works as intended, so to make the shifter "realer" all I needed was a simple stick, not a nesting doll arrangement.
The other night I got to work.
From what I can gather by photos, the real cars' shifters were about an inch and a half taller than the one I was using, including the extension I scabbed on during the build.
Out of the spare parts bin I grabbed a likely-looking old shifter and cut off the ball end.
The shaft screws in with a 3/8-inch threaded rod at 24 tpi; standard SAE fine threads. Of course I had every kind of bolt but that one, so I ran to HD and spent $3 on two Grade 5 (they didn't have 8) zinc-plated bolts.
Cut off the head of one. Drilled out the bottom of the cut shifter and mocked up the parts.
That loop thingie is what controls the big fore-aft cable. It's about a quarter inch thick. I was going to use a nut for my version but found a piece of quarter inch plate with the requisite quarter-inch hole drilled through it on my work bench. A little surgery with the angle grinder and...
Shortly:
And then:
Once installed, the loop for the cable keeps it from backing out.
The only thing missing now is the correct mushroom-shaped knob. I believe they are available commercially, but if anyone has one loitering about their spare parts bin, I'd sure like to have it. 12mm threads.
