1974-1978 Mustang II U joint - parts books wrong here too..
Here's another glitch in most U-joint listings for 1974-1978 Mustang ii
The ford parts book lists the U-joints as follows:
1974-1978 Mustang II U joint (4602 driveshaft)
E C3AZ 4635-E CLEVELAND 1310 (FRONT JOINT - ALL 1974-1978)
1-1/16" x 1-1/16" : 3-1/4" x 3-1/4" (269/280/379/380)
F C3AZ 4635-F CLEVELAND 1310 (REAR JOINT - ALL 1974-1978)
1-1/16" x 1-1/8" : 3-1/4" x 3-1/4" (497 a combination of UJ513 x UJ369)
SKF catalog says 430 -- It does not match the Ford parts book.
