944 Axle Length - Early Auto Short

Hi,

I am in the process of narrowing the rear of my car (IRS) 1"

It will (obviously) need shorter axles.

Type 3 Square/Fast/Notch left-hand (short side) auto axles are shorter by about an inch.
Makes them a good option for narrowed rear ends..

Because I am running Bus/Thing/944 CVs,
Type 3 left axles won't work, due to the splines being different.

Has anyone out there used the early/steel-arm 944 auto short axles for this?
I noticed last time I was in the yard, that auto 944s have two different length axles..

For reference:
Type 3 auto short left side axle -- 15 5/16"
944 manual axles -- 26 1/4"
Bus auto short left side axle -- 18"
Bus auto long right side axle -- 19 7/8"
Late (1986) narrow aluminum arm auto short left side axle -- 20 1/8"

These numbers are just rough - made with a tape measure.
Obviously, I have every axle except what I need..

Anybody out there that can measure their early steel-arm 944 auto short left side axle for me?
Or know where to find details?

Please and thanks!

No idea on the 944 auto axles, but the splines should be same for the early 944/thing joints and type 1/3 axles. Its only the late 944s that had different splines.

The joint width is different betweem t1 and 944, but what I've done in the past is machine the t1/3 axle a touch on the shoulder to make the wider 944 joint fit. Or leave off the bellville washer and clip of you dont want to machine.

Just some options...
