Rear shift coupler rant... (I got better)

I haven't messed with the rear coupler in a while, but iirc the boot is easier to get off of the coupler when the shifter is in either 2nd or 3rd. I think one of those gears makes it easier to push it back, but I can't remember......., it's late and I might be just dreaming .
Damn coupler
btw, why are you replacing the coupler?

The bushings have gone byebye. I'm amazed at how much shift slop this creates.

Quick update
That set screw will come out if you go at it easy with lots of heat and kroil, rinse and repeat. Took a few days but finally got out the bugger screw. Anyway, for BrendanC I've decided to post a couple pics showing what all the fuss was about. You will also find the tools req'd. 4mm hex socket and key.
Notice the new coupler w/bushing next to the old coupler. Wow, can you say sloppy shifter? If so, might want to check your's out.
I'm including the link to a Nichol's tip which covers the basic in and out of this job. Here

I thought you could buy the bushings separately now? (928 specialists?). I made my own out of hard rubber stoppers from Lowes. They've lasted for 5+ years.

I don't think the boot is all that necessary, as the coupler is up over the torque tube. I have kept mine, but that is a safe, clean area up there.

Yes, you can just buy the bushes and press the pin out, install them, and press the pin back in. I was concerned I may have to destroy the coupler to get the the set screw out.

FWIW my original coupler looked like your new one from the outside. In my case I think the pin was fracturing, causing sloppy shifting even though the bushings looked good. Eventually the pin went AWOL (see the pic earlier) and putting in a new coupler made a night-and-day difference. Heat, Kroil, a good 4mm socket with a long wrench, and careful steady pressure.

I had the pin fall out of one at the track...I was not happy . The replacement bushings are for a 911 and are not the same as the original ones used in the 928 coupler they lack the slight fore and aft slot. What was that slotting for ?? I Mc Givered the coupler and still ran the car Installed a new coupler shortly thereafter.

FWIW, I had a little slopiness in my shifter so I thought maybe it was the coupler.I removed the coupler and the bushings felt tight except for the engineered slot in them,so I made a set of replacements out of Delrin without the slot.i put it all back together and the difference was night and day.The shifter was tight and definite.That mod added with the short shifter really gives the feel of a racer.

Just removed mine as the first step of getting my short shifter installed. My set screw was not as much of a beast as it was for others, though I did try it without applying heat first and it would not turn. Sprayed the hell out of it with PB blaster and let sit for a while (maybe an hour). Nada. Apply heat = turned almost instantly. My boot was no longer present.
My coupler bushings are pretty comical. Or rather, what is (not) left of them!
Tools list:
13mm socket & wrench; deep socket worked best because a short socket was too short but with an extension it was too long
5/32 allen wrench/bit (used a bit in a normal wrench)
PB blaster/WD-40/Rost-off (caution... most rust penatrants are flammable!)
Blow torch
Flashlight
PS: this was my first opportunity to use my new-to-me liftbars. They are sweeeeeet. I was lucky enough to get a set second-hand.
