sorry

I need the ducting for the eyeball vents and defroster. I Googled Mcmastercarr and got a lot of hits but nothing specific to car parts.

This is the ducting that goes to the eyeball vents and defroster. I tried Nissan and was told that they no longer carry it.

I will be contacting them this week if the mechanic cannot get one of the two tachs I have to work correctly. Thanks.

I had the same problem with two seperate 240z tachs, one was 200 rpm off and the other was 600 rpm off. The one that was 600 rpm off had just been rebuilt. I got a schematic of the 240z tach off of this forum. When I gave it to my mechanic he was able to adjust both tachs so they read correctly. If you want a copy and can't find it in the forum, let me know and I will find a away to get you a copy.

Hi, I need a replacement right side under dash duct for my 240Z ac. Several months ago I noticed a complete set of under dash ducts for a Z but did not know that I needed them at that time. I have been looking for a month but have not found anything. Is there a generic after market product that will work? Thanks, Ron

Hi Andrew, Thanks for the info. If I cannot get the tach working soon I will probably go back to stock points also. Ronald

Hi tlorber, Thanks for the info. Can you tell me how to contact the speedo shop. I live in central California and would mail or hand deliver my tach for the mod. I would gladly spend the $170 so that I can have a working tach. Ronald

Hi, I received some great past help from this forum regarding an engine miss after installing a Pertronix electronic ignition. After trying all of the suggestions, the mechanic changed all the connectors to the tach and the miss finally went away. I purchased a used under dash wiring harness for the connectors. The tach still had a problem with cutting out above 4500 rpm during fast acceleration like it did before. The mechanic hooked up a different tach and it did the same thing - cutting out above 4500 rpm. Now the tach doesn't work at all but the car still does not miss; the needle doesn't move at all. The mechanic will try the other tach next week to see if it still cuts out above 4500 rpm, or does not work at all. My 240z runs much better with the Pertronix system but this tach problem is very frustrating. If the tach problem can't be fixed I am thinking about removing the Pertronix and putting the z back to stock. Any ideas on the tach problem? As an added note the mechanic replaced all of the dash light connectors with connectors from the used harness and fixed a long term problem with intermitant dash lights. Thanks in advance for the help, Ron

Thanks for the input. I will try it. Ron

On the schematic that zcar70 supplied it shows a speed adjustment. It that the recessed black slotted item just to the left of high center on the back of the tach? I have two tachs. One is over 200 rpms off and the other, just supposedly completely rebuilt, is 600 rpms off. Will that speed adjustment adjust the rpm reading on the tach?

Thanks for all of the suggestions. I will try them all. I will check the wiring for proper connections and being wired correctly. I will check for slop in the distributor. If that does not work I will try the resistor. On the schematic that zcar70 supplied it shows a speed adjustment.

I have a 280Z block, 280Z five speed, and a 280Z rear end in my 240Z. I know that in theory that should not create a problem with the tach. However, the car gets up to 6,500 rpm a lot faster than with the smaller block and the standard point distributor. Could the old tach just not be able to take it? Thanks again for all of the help. I have some other nagging problems that I will bring up once I get the missing and the tach problem resolved. Thanks, Ron

duffman, My ballast resistor is still hooked up. The schematic that I am looking at for the Pertronix conversion shows that it should be hooked up. Ronald
