61mm factory LSD Flanges

[knapmann]

I have a pair of coarse spline transmission flanges for use with the factory ZF LSD used from 1969-71

These are 61mm long on the shaft section rather than 56mm of the std flanges. I believe these are very difficult to find.

...for use with the factory ZF LSD used from 1969-77?

These are for 1969-71, and not 1972 or later.

Thanks for the info, maybe you can school me further as I can find very little info on these? I thought that the same diff was used from the 901/13 in late '69 through to when the 915 went to 8:31 R&P in the mid 70s? if my thinking is wrong, what is the difference between the 69-71 flanges and the 72+ flanges.

...what is the difference between the 69-71 flanges and the 72+ flanges.

The width of the axle CV joints changed in '72, and a corresponding change was made to the flanges.
Flanges from '72-on have 915 numbers, then 923 numbers from '76 until the fine-splined versions.
