What does this suspension arm fit?

I have had this hanging in my shop for many years.
Can anyone tell me what it fits?

Rex- Looks like a Royale RP33 front rocker maybe. 81-82 Van Dieman front rocker or Royale RP24 front rocker. Just a guess.

Thanks, Mike, that's a start.

I had been intending to drop by your shop and ask you, but never got around to it.

Thanks again

Rex

You can rule out RP24, I have one and thats alot different than what is on it.

Not a VD RF81-82

Early Ralt RT1,4,5

Ralt RT-1/3 did not have rocker arms.

If I'm seeing these correctly the pictures are of the bottom of these arms.
Left and right shocks are mounted vertically in the middle of the car....

Something like this:

Google brought up a Royale RP33 image that looks pretty similar:

It looks like a RP31 to me.

From the photos you guys linked, it appears RP31 & RP33 use the same rockers, and they do look like this one.
I had looked at those photos (and a thousand more) but just did not see it.

Thanks for the clues!

definitely later Royale
