[NLronald]

Hello all,

I just arrived here: http://67-72chevytrucks.com/vboard/s...d.php?t=698493

I'm searching for a original steering wheel for my C20. At this moment it has this one:

The photo's also show how it is mounted.

Question:
- what steering wheel is original in this car?
- Can it fit "as is" or need I a adapter?

Help is appreciated

Greetz, Ronald.
