Hey Lars,

The year/make/model/weight rating my have a bearing.

Mike shotgunned wonderful spec's, very impressive...

Made me think of a kit I just came across in my storage for a 7360.

It is what is called out, or specified for a 1978 K10.

This kit has two seals, upper and lower, with washers between.

This one measures 1 1/4" shaft size, and larger OD, width.

See if you can get more specifics so we can compare notes, Okay?
