Saturday saw some slow progress....
It was more a case of measuring and figuring out how to create the best 5 lug rear conversion. I want this to be as factory as possible, i.e not re-drilling hubs etc. To this end, i've devised a cunning plan, a plan so cunning you could pin a tale on it and call it Le Renard!

So first off we need to stip down the CV joints. Here you can see after i've scrapped all the stinking grease off the spring/ circlip that keep the little bug*er from falling off.

Then it's just a case of using a drift and tapping off the joint.

Once off and cleaned up you are left with the drive shaft.
After much head scratching, internet research and measuring we end up with this combo.

What we have here are very narrow year specific parts. The 5 lug hubs are from an early 911 (1972-3) outer 5 lug hubs mated with 911SC stub axles.

Sat here on the bench next to the old stuff you can see everything matches. The height and dimensions are bang on :thumb:
Old stuff on the left and new old stuff on the right.
Now for the tricky bit (And you though this would be a breeze!)
The new old set up has 6 holes on the CV joint and the old has 4
Now the plan is to use 944 CV joints which (if I get the right ones) have the right drive shaft spline count and 6 holes to suit the stub axle. HOWEVER they are wider....

I think it's 4mm. Doesn't sound like much I know, but remember that circlip in the first photo.......Arh, now you get it, right?

So, my idea is as follows....

You can see the circlip groove arrowed. Obviously the 944 joint being wider won't allow for the clip, so i'm going to lathe 4mm (2 red arrows) to allow the joint to slip further onto the shaft.
I will do this both ends to allow 944 CV joints to be at the gearbox end also. This will mean finding drive flanges for the box, but I think this is a neater solution and gives the added benift of CV's that can take at least 250 ponies. I think the standard ones are good for maybe 150-60 at best.
So I need to track down some more parts however I think this keeps everything neat, simple and tidy. I can build up both complete drive shaft assemblies and just store them for later in the build.
So, there we have it for the moment. I call this progress although not a great deal has happend, just one thing less to have to ponder
All the best gents,
