Which shift boot are you using with your short shifter?

Post by QuintupleTurbo »

Hey all,

As the title says, I'd love to see your setups with how your short shifters / shift boots are set up in your Spiders!

The PO of my 124 installed a Michigan Short Shifter (It's a perfectly straight short shifter piece, no angle with the knob facing the driver, the pics that I've looked up indicate that maybe the Michigan Short Shifter is a little different?)

Anyway, I bought a new shifter knob and a new black leather boot from Auto Ricambi, and I was planning on installing it today! Sadly, between the poor excuse for a circle that's in the console shifter plate, the 50 year old shift boot retainer that's basically shaped like an octagon with fatigued corners, and the "taper" of the shifter boot, you could say that I'm having one hell of a time getting it to properly mount. :mrgreen:

I feel like I may need to return this leather boot for something from a third party. The reason being is that if I install the boot at it's stock length, it's incredibly bunched up with the short shifter. The leather is also so stiff and bunched above the shifter plate that it feels like it's going to prevent smooth shifting into 2nd and 4th gears. On top of that, the shifter knob is pretty awkward to grab with the boot all bunched up around it. The knob looks like it's wearing a turtleneck.

If I pull more of the boot through the shift plate, two things happen. 1) The diameter of the boot gets slightly smaller as it gets higher, which makes it very difficult to get the shift boot retainer ring to expand. I haven't had any luck getting the ring to actually properly mount when I do this. 2) The excess material doesn't make it easy for the console plate to press down and fully close, which may cause more problems getting into gears at the bottom of the shift gate (2/4/R).

I'd love to see some of your setups if you've got photos of what your shifter/boot combos look like! Otherwise, feel free to chime in with what your setup is.

Cheers!

I think I would approach it the same way that you have, and yes, that "poor excuse for an octagon" is rather lame. Not one of Fiat's better designs... A few thoughts:

The shift boot isn't that complex, and a good leather worker could probably make you a custom one although it would likely cost more than an off the shelf item. In fact, depending on how complex you wanted the shape to be, you could probably make one yourself by cutting the leather and then sewing a seam along one side. There are calculators out on the Internet to figure out the size for a cone, and it's probably similar to the process I used to make new speaker cones for old radios. You need the base diameter, the inner diameter (where it would attach to the voice coil), and the height. Takes some practice but works quite well, and likely would be similar for making a shift boot. Practice on some cheap vinyl before moving up to leather.

The suppleness of the leather is a factor. If it's too thick or too stiff, it won't shift well. Not sure what your AR boot is like.

Bryan's Poor Man's Method for replacing the octagon shift boot retainer: Get a wide-band screw type hose clamp, turn it around so that the screw is on the inside of the band rather than the outside, and then expand this clamp in reverse to press the boot against the opening in the shifter plate. In my case, I had replaced the shifter console plate with a solid 3/8" piece of hardwood, and I used several tiny wood screws to secure the hose clamp once installed and tightened. Make sure the worm gear is positioned so that it doesn't interfere with the shift lever.

What a genius idea. Just went to Home Depot and spent $2.50 on a poor man's retainer. I don't think the worm gear will interfere with the shifter when it's on the left or right side of the opening, but I'll play around with it later.

I ended up cutting the excess leather off of the shift boot, and using the hose clamp to stretch the leather a bit to snugly make its way around the opening. It should work well! Thanks again.
