I have a question. If you're putting Brand X engine into Brand Y car, how do you ensure the driveshafts are compatible with the output of the transaxle? Are they somewhat "standardized", or are you committed to either making the Brand Y driveshafts attach the Brand X output or do you use the Brand X driveshafts and make the Brand Y hubs fit them? Is there some sort of reference chart available on the web?
I have used the rock auto parts catalog for this by checking descriptions on the vehicles in question for dimensions and spline counts. I've been lucky enough so far that dodge seems to have used the same splines forever.
The other option is swapping new inner joints to the shaft, It would not surprise me if there are just a few of the axle shaft splines used in most applications.
In reply to stroker :
They are not standardized, though within Brand X there's likely to be reuse of a pattern.
I don't know of a reference chart, but I'm sure there's discussion, here and elsewhere.
I think there are a few particularly well-known patterns that aren't standards as such, but e.g. I think Quaife and other similar gearbox makers offer a "Porsche" output flange pattern, and perhaps one or two others.
Seems like it's not uncommon to wind up in the position where between CV types and required lengths, custom axles splined for Brand X's CV at one end and Brand Y's at the other are the best answer.
Generally you just call up Drive Shaft Shop and tell them what you're doing and you're out anywhere from 1500-2k.
