Aftermarket steering brace for the 18B

[VintageMA]

I think you may be thinking about the RC18 drag link that used to be made by Driven Productions. I had to dig up a billing invoice from early 2006 to find this but their site drivenpro.net doesn't seem to be around anymore.

You may be able to find something on e-bay.

Here's a few items I found that I used to run on my RC18:

Hope that's what you are looking for - do a search for drven productions on e-bay and you;ll find a few different products.
