I setup my car to use a monoball for the shift rod but was unhappy about the lack of a boot to prevent the road grime from getting in so I machined an adapter out of a solid chunk of aluminum to be able to use the boot. Should work great.....

Now thats awesome.

Did you make everything from scratch?

I like the monoball set up. Installed one on a 914-6 this year and it makes a difference. I like your boot set up, that was my only complaint was you couldn't put the boot back on. Nice work!

Where did you get this mono ball for the shift linkage?

Very nice.

I didn't know that this monoball unit was available. I was thinking of making a replacement bushing out of brass, but that thing is much better.

Nice finish on your boot adaptor. CNC or manual lathe? I would think that Patrick Motorsport would be interested in selling what you have made.

Cheers,

that looks great Paul !!!!

I have the mono-ball on mine. I haven't really used it yet, but I'm concerned about the steel to steel contact/wear in regards to front to rear shift rod motion.

The spherical bearing takes care of the rotational axis, but the sliding motion is metal to metal with only grease to control wear. I'm using a commercially available marine boot to cover mine. It looks like a mini shift boot and fits the diameter of the shaft at one end and has a mounting flange that covers the bearing at the firewall.

I guess time will tell on the wear??

Here's a pic of the boot, they're only a couple of bucks:

Oh yeah............Really nice work Paul !!!!

On the wear issue, something to think about. I had a brain fart when I was machining my shaft down to the right size for the mono-ball. Machined it twice and it was still too small...ha ha

I cut the shaft and made a new solid piece for the end and pressed\welded into the tube and re-machined to the right size. I was thinking it would be really easy to machine the solid piece down a little more and press a piece of bronze over the top to have a bronze bushing to wear on the steel mono ball. Then I thought I was being anal and blew it off as being too picky....hmmm maybe not.

You could not do that with a stock shaft as the tubing is not thick enough in the wear area.

Fin, I am sending Patrick one for his Mule car....

Paul, Does the boot your using need the stock rear shift bar? It looks like the stock boot that fits to an oval flange on the bar and my PMS bar doesn't have this flange.

Just curious?

I have 2 boots that will work.

1. The one shown and I would cut the oval flange out of the stock rod and weld it on the rod that I make.

2. I have another boot that has a small round end that I think would work fine as well.

Once my engine\tranny is installed and I know what I have to miss, I'll decide on the final version. 3.6 is supposed to ship today so it won't be too long.....

Another thing that worked good was I silver soldered three 6mm bolts in for the mounting. I "pre tinned" the head area of the bolts and then slid them through from inside the cab through the firewall mounting holes. I spun a nut on so I could clamp it with vice grips to hold it in place and finished silver soldering. Now I have 3 studs sticking out and will never have to get inside the car to remove or replace the unit. My car is only primered so this was the time to do it.....
