According to http://www.924.org/parts/parts.htm , 924 CV joints _are_
bus joints (113 501 331D), but the p/n given is for a Type 4 joint. I
think they're confused. According to
http://www.doghouserepair.com/mall/description.php?ItemID=7824 , that
part number uses 0.6875" diameter balls.

VW changed the balls in the Bus/Vanagon CV joints from 0.750" (19.04mm)
to 20mm with p/n 251 598 101 in 12/1984 (see tech bulletin 87-01 @
http://www.vanagonparts.com/tech_bulletins.html ) VW no longer lists
the .750 joint, it is the 20mm joint that VW now lists as a replacement
for the older breadloaves and Vanagons, too.

Ratwell ( http://www.ratwell.com/technical/FAQ/FAQContent.html ) says
this:

"Here is a list of maximum angles that the hub of the joint is allowed
to move compared to other models:

"bus, 18 degrees
"411, 22 degrees
"Porsche 930, 28 degrees"
