The washers are serrated belleville, and are originally dished to create a stronger
"clamp" when the CV bolt is torqued. I think you can get them at McMaster-Carr.
I think another good mfg'er of these washers is Schnoor. A resource for the
schnoor: http://www.metricmcc.com/
If you cant find a CV boot clamp, use heavy safety wire as a clamp. I put 2 of them
on my last CV repair in the absence of a proper clamp .... truth-be-told, I also used
2 metal coat hanger wires on another boot and it is surprisingly holding up nicely.
The biggest difference with these Vanagon CV's and the CV's on other vehicles,
is when we start doing engine conversions, larger wheels/tires, which all increase
the axle-to-transaxle angles and that puts more "resting" angle on the axle, and
when we go over bumps, these angles increase and put more strain on the boot.
The CV end of the boot stays attached to the CV, while the axle path pulls the middle
of the other end of the boot away from the CV end .... constantly.
bob ... I've already tried various sizes of zip ties for this purpose and they do not work
at all, at least on my van.
