Bolt difference? v.manualconversion

[Six_Shooter]

I haven't seen a yes or no answer to this question:

 

Is there a difference in the bolts between an automatic (flexplate) and manual (flywheel) on the Datsun/Nissan L6?

If there is, what is the difference (in length)?

 

For reference the engine is an L28 from an '81 or '82 280ZX, installed in a 1973 240z, that has, as far as I know, the original automatic tranny.

 

I'm used to GM engines and trannies that use a different length bolt between automatic and manual, and is why I ask.

 

Since I have most of the manual conversion parts and some on the way, this is one of the last things that I need proper before I tear into the conversion.

I only know of one crank bolt pattern........... Dont know if the bolts are different.

Now I understand your quest for a flywheel...

Yeah, from what I've read the pattern doesn't seem to be an issue, but, I haven't found any difinitive information on the bolts themselves.

Well I looked at the fiche, and there are three different bolts litsed for the manual, depending on the date, and two for the auto, also depending on the date. However one part number from each, matches up.

 

Manual L24 up to 11/72 P/N 12316-21001

 

Auto L26 from 08/73 P/N 12316-21001

 

In both cases the P/N could be 12315-21001, the fiche is pretty blurry.

 

In any case it looks like the bolts from the flexplate will work with the flywheel. I hope they will anyway, since that's all I have at this point.
