Having worked as a mechanic for 8 years or so I have been thoroughly unimpressed with "remanufactured" electricals like starters, distributors, alternators, etc. If you go to an automotive electrical specialist they can do a good job, but your typical auto parts store job is crap IME.

I'd rather reman it myself, especially in the case of a distributor where I think the most likely procedure involved in your typical reman job is cleaning it and putting a new dashpot on the vac advance mechanism. I've actually seen with my own eyes (enough times that I know it wasn't a fluke) a "remanned" part that has been SPRAY PAINTED SILVER RIGHT OVER THE CAKED ON DIRT instead of being cleaned properly!!!

montoya_fan01 is right that a ZX distributor will 99% need a little attention to the vac advance mechanism at the very least, but they're very easy to pull apart and if you do it yourself at least you'd know it's been done correctly.

While I concur with your opinion of reman parts from the local auto parts store, I also believe that you won't have any such "quality issues" if you stick to the Nissan Reman Dizzys mentioned in previous posts. The ones that I've purchased (D612's) have been absolutely first rate.

Hello Friends

I wonder if anyone know OEM was dual or single for my Oct 71 production 72 240Z ?

If it single, Is it easy to modify dual to single ? How is the deference of performance between single and dual.

sorry it might be poor question some of Z car expert but I am interested in basics of Z car.

Thanks
