Anyone have the actual 914 axle length off the top of their (lavender mohawk) head?
I also need the spline count for an ass-dragger CV/Axle. Come on East coast Rich Brianiac(s)... make yourselves useful!!! (IMG:style_emoticons/default/w00t.gif) Why? I'm looking at getting custom axles to use with 911 (coarse) tranny flanges, 911 CV's and 911 stub axles. |

Eric,
If you're looking for a one-off, you can source 911 coarse-spline sportomatic flanges and use '72-'73 911 axles/CV's. I recall the difference in axle length is about 1/2". The sporto flanges make up about 3/8" of that. |

914:
20 1/4" Overall length compressed ..... 33 splines each end of beam for bearing cages 911: 69 - 71 ... 19 1/8" Overall length compressed ..... 28 splines each end of beam for bearing cages 72 - 75 ... 19 7/16" Overall length compressed ..... 28 splines each end of beam for bearing cages. |

OHhhhhhhhhhhh... LOOKIE WHO WOKE UP!
Welcome back Rumpleslitskin. And HELPFUL at that!! (and ya beat out the right coasters... very proud) (IMG:style_emoticons/default/wub.gif) Thanks Ron-O. I think that's all I need but, I kinda do and kinda don't understand "compressed". If I were to get replacement axles themselves, wouldn't I want the actual axle shaft length of a teener, compressed or not? I realise the CV's may extend beyond the axle shaft so compressing them would give me... the actual measurement of the shaft? If so... I guess I need 28 spline axles in the 20.25 length. Right? (IMG:style_emoticons/default/confused24.gif) Thanks Gary. I have a pair of coarse splines bolted to the box right now. I think I can get some off the shelfers that may fit my need by using those. I'll let you know what I come up with. Thanks Paul for the guidance. |

All CVs are measured compressed .... you are correct.
In this case, the compressed length is the Beam length due to their construction. Sorry (IMG:style_emoticons/default/yellowsleep[1].gif) |

late '75 to '84 cv's are 25 spline, just like 914-6 axles, and are $82 at PP. early 911 cv's are $280 (IMG:style_emoticons/default/yikes.gif)
"85 to '89 cv's are 28 spline, but have huge diameter and won't fit your coarse flanges. |
