What is everybody opinion on how much a used radar arch off a late 80's KV Scarab is worth. I have an opportunity to purchase one and have no clue what to offer the guy. I know that I could have a new one made by the company that made them for Wellcraft for $7000.00.

I have no idea what they are "worth". Most people who buy older boats with arches want to take them off.

Its not worth much in my opinion. There is a very very thin market for it and it is going to cost you time and possibly money to get it on your boat.
How much is it worth to you?

Go to "I bought a cat killer" Brad Zastrow said he just got an old fountain and took the arch off. Would it fit your boat?

Has anyone else bought a used radar arch? Was it one that was a direct fit for the boat or did you have to make it fit?

I'd say $200-$300.

The last one I had I gave it away, and gladly helped him load it on his
trailer.

Paint it gold and sell it to McDonalds.

Try the Sonic forum . . .

I've got one if you want it. It's just a wall decoration in my shop.

If you are intrested, I'll measure the width of it and the hight.
