" I do not have the window frame installed yet. " Install the window frame and adjust as needed. All frame bolts must be tight as they pull the frame into the correct geometry. Here is a book that I used to to do two 240z restomods. Gives details on how to disassemble, restore and reassemble a 240Z. Lots of pictures with step by step instructions. How to Restore Your Datsun Z-Car by Wick Humble available on Amazon

I never had success with Vintage Rubber hatch or windshield seals on two 240z projects. I ended up using stock OEM seals. I recall getting the OEM seals from Courtesy Nissan and Motor Sport Auto (MSA). The problems I had with Vintage Rubber were deformed corners making it impossible to install. I used the rope trick and installed the stainless steel center trim in the windshield and hatch seal before installing the seals using the rope trick. Also, Vintage Rubber door seals were too thick making it impossible to close the doors. I went to Pep Boys and bought generic door seals that squeeze onto the door opening pinch welds. The problems with Vintage Rubber seals has been known for over 20 years. Lots of info here on HybridZ. There is a company that makes the windshield and hatch seals without the center stainless trim.

Another option would be to use the 1979 Toyota 4x4 pickup front calipers for solid rotors which are plentiful and cheap. Using Carbotech AX6 pads with the Toyota calipers works well with my set up: 15/16 MC 9 inch dia 280z booster. Swapped the 240z brake pedal push rod into the 280z booster for stock connection to brake pedal. Front: Toyota calipers for solid rotors. Used SS braided line to connect hard line to caliper to eliminate the Toyota "S" tube. Rear: 89 240sx rear calipers with 1984 non-turbo 300zx rotors Carbotech AX6 pads front and rear

If you know the thread pitch of the bleed screws, could using "speed bleeders" be an optional replacement? http://www.speedbleeder.com/main.htm https://www.summitracing.com/parts/ear-280040erl The Sumitomo MK63 looks like a slimmer version of the Toyota 4x4 pickup calipers. Is the Sumitomo MK63 a direct bolt-on replacement for the stock Datsun calipers?

Try contacting the guy who wrote this: https://www.jdmjunkies.ch/wordpress/2021-01-17/240z-the-guide-to-sumitomo-mk63-brakes/ Looks current and there are commenters at the end.

My kit from Modern Motor Sports (out of business) used 240sx calipers and 1984 non-turbo 300zx rotors.

If the SU carb has an air leak, it will create a lean condition for which no amount of tuning will correct. The problem with the SU carburetors is that the throttle shaft becomes worn and allows air to seep past the shaft and into the carb causing a lean condition. You can try contacting ZTherapy who specializes in SU carbs and parts. Also they sell a video called "Just SUs" it explains how to repair and tune the SU carb.

The best performing pads that I have tried on my SBC 350 240z. I have tried all of the Porterfield, Hawk etc pads and they suck in comparison. My brake setup: Carbotech Ax6 pads work really well with this setup. Front: 1979 Toyota 4x4 pickup calipers for solid rotors. Direct bolt on. Rear: 1989 240sx rear calipers 1979 280zx 15/16 in. master cylinder 1978 280z 9 inch booster. Notes about Ax6 pads: Excellent cold bite which is great for a daily driver. Dusty at first, but I don't care. Stopping performance is what is important. No sign of fading!!! No noise Buy direct from Carbotech. Carbotech staff is helpful and courteous.

Hybrid search sucks. Copy and paste into Google search: EZ wiring kit install 240z site:forums.hybridz.org

Milesz I responded to your message before seeing this post. I recall members posting how to install the EZ wiring kit with instructions on how to, for example, connect to the TS/headlight combo switch etc.

Thanks for the fix and update.
