No expert on steering A but the systems you referred to are the same . Depends on choice .
I installed the Multiflex in place of the 55 year old pulley system and what a difference. It doesn't come with a steering wheel (thank goodness).
You should be able to use the same wheel .
The important thing is cable length (see instructions) as it comes in fixed lengths .
Still don't know what you current system is so as Mercman says you may only need new cable .
Send pics we love photos
As to House Paint . Gee you take me back a few years
