Replacing Half Shafts with CV

I have a question for those of you with CV axles.  Are you using Moon Plates and Schnorr washers to secure them?  And 55mm socket head bolts (a couple of threads showing)?  The plates provide a thick metal base on top the the thin CV covers and they cannot turn because two bolts go through them.  The Schnorr washers work with tension (not friction) to keep the bolt in place.  Apparently this is the best setup to keep CV axles from coming loose.  The washers are one time use.

Steve where or what vendor did you find your conversion kit from?

The CV axles and adapters are from Wilkinson.

I switched to cv joints (using adapter plates) about 10 years ago and they completely eliminated my vibration under hard acceleration. Your installation using moon plates (common in Porsche community) and Schnorr washers is probably better than mine. I used flat washers without moon plates and torqued using a small amount of red Loctite. Considered safety wiring but decided against unless one came loose. Couple of items for your consideration. 1. All CV joints are not the same . GKN Lobro is usually considered the best without going custom. 2. CV joints require packing with grease. I recommend using Swepco 101. 3. 108mm Aerodynamic or High Speed boots allow easier installation, torque of bolts and they are more compact . Good luck

FWIW, I installed the SACC Restoration CV-joint half-shafts a few years ago. I believe they incorporate Porsche 930 CV-joints. Plug and play...

I used Stage 8 bolts when I installed my CV shafts years ago. https://www.stage8.com/

Good information.  Thank you all.

It looks like these are Lobro CV's.

I was over at Larry Stocks shop in N NV recently and he's now making the inner & outer adapters for CV joint axles, supplied as a kit with bolts and boots included.

Everything is back together and I will test drive it in the morning.  Below you can see the 70mm bolts, Schnorr washers, and torque distribution plates on the CV's.  The bolts extend slightly out of the ZF output shafts ensuring that all threads are utilized.  The bolts are torqued to 60 pounds.

Success!  I drove the car on the freeway and the drivetrain was smooth and much quieter.  A bunch of bearing noise went away.

Great News Steve!.  Looks Good.  I have a set I will be using on my Pantera once I get there.  Larry

You may find those bellow boots don't last, if so change out for the aero / high speed style that can cope with much acuter angles.

The bellow boots also don't last long if you install the halfshafts with the "thing-that-subs-for-a-u-joint" in the outboard position, because that lump seems to be bulkier and gets closer to the hot exhaust pipe just below. The axles are normally symmetrical so you can mount them either way. With the heavier end near the ZF, the unsprung weight in the rear is also fractionally lighter for theoretically better handling.
