2+2 Hatch Release Trim Ring Help Please
OK, I give up! What’s the trick to putting on the hatch release trim ring. It has a notch that I presume goes to the rear for clearance of the lever portion of the release handle once it’s on, but how is it supposed to go over the handle to be put where it belongs. There has to be a way taking advan...

Re: Not a dizzy anymore
I'm assuming that you had those holding brackets 3D printed?

Re: Not a dizzy anymore
Looking at your picture of the coils, I can't tell if you are using the original heads with slanted spark plugs or the later heads with the straight spark plugs. I had thought of using GM coils similar to yours but they didn't seem to be able to deal with the slanted plugs. Just wondering how you de...

Update Re: Speedo Thread Size at Trans
My final solution was at the other end of the speedo cable. I bought a Daytona Motorcycle Speedometer Conversion Adapter to Convert Mechanical to Electric Speedometer (93390). Turns out that the rear of the speedo uses the same connector as is common on most motorcycles and is pretty much the standa...

Re: Speedo Thread Size at Trans
No, not digital speedo. I need the signal to feed into my fuel injection ECU (MS3 Pro) so that when I look over the data logs I'll know what speed I was at. I've been searching around and think I have found what I need. A little more research is needed to confirm, but Daytona makes what they call a ...

Re: Speedo Thread Size at Trans
Thanks for the thread info. The DAC4569 is a bit pricey at over $200 and doesn't really solve my issue(my speedo wouldn't work). There are adapters that are what you might call "pass through" in that the mechanical drive from the speedometer can still be attached and in between is a device that will...

Speedo Thread Size at Trans
Does anyone know what the thread size is on the speedo output at the transmission? I need to get a mechanical to electrical adapter so that I can feed speed data into my MS3 Pro fuel injection ECU. I see common thread sizes advertised for GM as 7/8"-18 and 5/8"-18. Not sure if either is a match for ...

Re: Brake slave cylinder
UPDATE! After working the brake 15 to maybe 20 times in the garage then going for a few 5 mile stop n go trips, checking levels each time before & after, it seems to be back to normal operation. I was really surprised there were any problems with this thing since it was new about 10 years ago, fille...

Re: Brake slave cylinder
Thanks Marek, you always have good advice. I didn't have this problem before, but the car has been sitting for quite a while and so I'm thinking that a bit of use may return operation back to normal. At least, that is my first plan of action, otherwise I'll have to jump in with both feet and pull ou...

Brake slave cylinder
I'm trying to find a rebuild kit for the brake slave cylinder. Apparently, mine has gone bad since the master reservoir is losing fluid and the slave reservoir is overflowing. So far, all I see are the complete brake servo repair kits at about $135. I don't really want to rebuild the actual servo it...

Front Shock Dimensions
I have searched in vain looking for what the bolt center to center dimension should be for the Series III extended front shocks. Surely someone can point me in the right direction.
Thanks

Finally got around to work on my Jag once more.

The more I look into this I'm finding quite a few different part numbers for what all look like the same mirror assembly. BD40822, BD41463, and BD43300. All with various /X versions for flat vs convex and who knows wha...

Remote Mirror Headaches
Anyone out there using the remote control mirror as used on the later SIII? It seems that now matter how I adjust mine, the best I can get is a view of the side of my car. once I have moved it to the max vertical, it starts going down as I move it to the left. I'm 6'2" so that has something to do wi...

Re: B W 12 Automatic gearbox
With Lucas injection installed, I think you should be looking at your AAV. This doesn't really sound like a trans problem.

Abowie: RE rear engine stabiliser, since this is a V12, there is no rear engine stabiliser. But the way the V12 twists under load when the motor mounts are hot & squishy, I have thought about maybe rigging something up along those lines. There ARE tapped bolt holes in the firewall and bellhousing. T...

Re: SIII Driveline Angles
Thanks for the pictures Bob. It appears that the engine sits level but it looks like the differential pinion angle is up, but how much? Oh well, the measurements will tell. lowact, as I stated in my original post, the JT5 uses a rubber mount instead of the stock trans mount. This is why I need to ma...
