:classic: You can remove the part from the car and bend the brake line over to each other and reconnect it. If you are using the 300ZX vented disc brakes up front and disc brakes on the back, you will most likely not need it. I have the 300ZX rotors upfront with S-12W calibers and 280ZX early calibers and later year rotors on my 71 240Z using the flat plate mount. I just removed it and have added stainless steel brake hoses to the front. The back hoses are still rubber. The system is very balanced for me. I use my car as a track car only now and like it a lot as is. Give it a try and if you don't like it, add the adjustable one to it later if needed. Bleed the system real good after doing all of this to it. The pads I use on front are semi-metal and the backs are organic. Stops a lot better then my old brake setup by far.

:hurt: The 300zx disc brake conversion is easy to do. Getting the parts for it is the hardest part for it. I have done this conversion three times now. First you do not need to turn the rotor down. It will work as is. Make sure the calibers read S-12W on it. There is another set of calibers you can use (S-13W), but I haven't done it with those. The 240Z hubs only need a 1/2" or .50 spacer and the 280z hubs only need a .350 to .375 spacer to make it work, it goes between the hub and rotor. You will need longer bolts for this. You should be able to pick them up at the local hardware store (just take the old ones and tell them you need then a 1/2" longer). Unbolt the old single plate disc from the hub and remove (clean the mounting area). Now mount the spacer and new vented disc to the hub (make sure you torque it down to spec's). Now place the calibers over the disc, it should bolt right up (if it does look centered, you may have to space it over with washers). After you have centered it and torqued it down, Look at the different location the brake line goes in. You will have to bend the line by hand to get it to fit. Take your time and don't kink the line. Replace the line if you do. After getting it all back together, make sure you bleed the lines good. If you convert to the bigger MC. You may have to adjust the pushrod on the MC to get the proper pressure to the lines. This is a great racing fix for the 240Z. I have it on my 71 240Z now for the past 10 years. I even went to russell bleeders so I can bleed faster at the track. I also have the 280ZX disc brakes on the back. The 300ZX rotors only move toward the inside of the wheel and does not affect wheel offset. You may have to go to 15" rims to make it fit. I am running 16" rims and don't have any problems with them. Good Luck, Rich. :beard:
