Thought I'd take a look at shafts last night.
The Pug ones seem not quite long enough so figured I'd take the inners apart:

Surprises (for me).
The inner CV has a spring in it. This pushes against the shaft. I was wondering WTF is this for ??
Then figured that the part that goes into the gearbox doesn't have any real retention on it.
Honda inner CV's have a clip on the end that locates into the diff and locks in place. To remove them you need to lever them out of the box.
For the PUG it appears to use the spring inside the joint to push the joint into the gearbox and maintain the seal / location.
So that's something else to bear in mind when building them!!

Accord shaft top and pug shaft bottom. From tip to end the accord is longer by about 20mm. That 20mm is needed.
So drum roll, spline count on accord shaft 32, spline count on Pug shaft 34
They happen to be the same diameter. If I can find a spider/tripod/bearing combination that fits the pug CV with 32 splines this will be piss easy.
The accord has bigger CV joints and thus bigger bearings (diameter). So now I'm looking for smaller joints from mine and others Honda parts to see if we can come up with a combo that works. Honda B or possibly D series stuff will be smaller than the Accord F series. But then they are 30spline, and the legs on the spider may well be smaller dia too
This isn't easy...
The bearings on the spider for the pug has separate needles, for the honda they are typically one piece spherical items.
I've not tried the pug needles on the honda spider yet as I have concerns over the way the honda spider is tapered at the end for the needles would be in free space.
