Steering Wheel Shaft length

[Frog76S]

Hello Pelican Brain Trust,

I’ve got an 88 911 and I’ve replaced the OE four spoke Carrera steering wheel with a four spoke Carrera hub extended steering wheel. I had Dallas Steering wheel make the grip thicker otherwise it’s stock.

I’ve owned the car for 8 months and the nut holding on the steering wheel was rounded so I replaced it with a thicker nut (twice as thick as original) to provide the socket more gripping surface. It’s much easier to tighten. I’ve noticed the four spoke has a little less room to navigate the socket due to the smaller opening in the center of the steering wheel as compared to a OEM three spoke steering wheel. I had zero issues trying to keep the socket on the nut with a three spoke steering wheel.

My question - Did Porsche extend or elongate the steering wheel shaft to account for the extended hub or are they the same length on all 87-89 911’s? The steering wheel shaft threads don’t completely fill up the thicker nut. I don’t believe this will be an issue as long as it’s tight and I’ll check it occasionally?

What say you and thanks for your time reviewing my question.

They are the same.
