OK, so I'm ready to install the engine and found a surprise. The PO was going to install a later model trans. As such, they installed 915 style stub axles. The oem stubs are lost in space.
The existing stubs don't bolt up to the 914/4 axles and CVs I was going to use. The 2.0/6 "S" spec motor puts out about 140hp. So I wasn't worried about twisting them with high torque since I used this set up with a 3.0 in the past. My questions is....are 914/6 AXLES which I might have access to, compatible with 915 sized CVs? FYI 914/6 CVs have been NLA for 20+ years.... Since I have the sub axles, can easily find drive flanges for the trans, I was thinking this would be an easy alternative. Does the 914/6 axle have the same spline count? 28 is what I've been told. Simply using a 911 axle won't work, too long. Buying 914/6 stub axles is an expensive deal, $5-600. Mittelmotor and Otto.... Some good news, I HAVE been able to locate one stub axle...it will need a little machining as it's a bit corroded. But I'm looking for alternatives. Anyone BTDT? Or even better....an orphan 914/6 stubbie? |

Further research shows 69-77 stubbies are the same.
Here's a set from eBay. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...RK%3AMEWAX%3AIT |

Further research shows 69-77 stubbies are the same. Here's a set from eBay. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...RK%3AMEWAX%3AIT I tend to think those from that ebay listing are not going to work. Those are early 911 stub axles and probably only work with hubs that are not commonly used on 914 five lug rear conversions. I also don't think the 69-77 911 stub axles are the same. In short, you hubs and stubs need to match (spline count as well as bearing width/ID). Your stubs and CV needs to match (bolt pattern/CV diameter). Your CV needs to match your axle (spline count) on both ends. Your axle needs to be the correct width. Your CV needs to match the transmission output flange (bolt pattern/CV diameter). Your output flange needs to match your transmission differential (spline count, mounting depth and probably other factors). |
