Non adjustable feehorn F/D?

[coinmaster32]

I have a chaparral feed that does not have an adjustable F/D. Does anyone know the F/D of it so I can set it on a new one?

I have one of those, I compared the distance the throat sticks out to the adjustable feed I was replacing and they were the same, about 3/4 inch. I bolted it in place, worked fine. If you have a button hook feed you can slide the whole assembly in and out for optimization. With support arms you might play with spacers or washers to improve it.
