Corse I CV joints

My brothers Astra rally car has them on the rear to stop the beam dropping to much and the springs coming off their seats.

Yes, the Corse I design seems always to have been in a state of flux. You can see differences in virtually all photographs of the early cars and not just between the Honda and Alfa engined cars. Damper and spring lengths were never sorted properly and those triangular top mounting plates front and rear just added to the confusion. Lionel just ordered part numbers supplied by Hugh Carson with out much thought as to if they were right or not. IIRC we tried different lengths of damper on Micks first car but he resolved matters with extra bump stops in the end. Steve Ellis fabricated new damper mounts front and rear.
I guess the lesson is for anyone building to check suspension movements very thoroughly with the springs off to make sure nothing binds up or reaches the limit of its travel throughout its range.
Looks like you have the part numbers for new joints now Steve? Shaft length is another matter.

The original inner and outer joints both had single circlips on the drive shaft with 2 holes in the end for circlip pliers.
The new inner - Alfa - came with the same style circlip.
The new outer - Ford - came with something that looks like a concave thrust washer and a circlip without any holes.

Does anybody know what I do with these 2 parts, or do I just replace the original circlip?

EDIT
It is for certain applications, but not how I will be using it. So original circlip back on.

Changed the bearings
Got the dampers back from AVO. Had the damper rods shortened by 1.5 inches.
Added 2 more bump stops to each damper. They now have 3 bump stops each - shows how wrong the damper top mounts are in respect of wheel/body position.
Put it all back together and lowered the rear of the car about an inch (was high before to avoid hitting body as I didnt have enough bump stops)
Have about 2" suspension travel in compression and about 2" in extension
Drive shafts at much better angle now.
At full droop now have 1-2 mm of shaft plunge
Car feels a lot better, and no noise.
