Van's Response:
Darrell,
Some of our customers have chosen to purchase the
RV-9 flap push rods to use on their RV-6/7/8 aircraft,
part number VA-256 $12.00 each -threaded hex rod. In
order to use those you would have to enlarge the hole
where the pushrod goes thru the fuselage. Also, as
this piece was intended for the RV-9= larger flap, it
will be too long. So when you trim the hex rod down,
you would trim a little off each end. If you trim it
all off one side, you may cut off all the threads.
This modification doesn't hurt anything of course (as
long as the rod is installed correctly), but it isn't
necessary.
We are, of course, always happy to sell more parts!

If you're looking for a more robust flap pushrod, why not just go with
steel, the same dimensions as the aluminum tube that's called out? That way
you don't have to change/enlarge the hole in the fuselage, and weight would
be about the same as the fat hex stock type.
I still have aluminum tapped flap pushrod tubes after more than 1000 hours
and easily as many cycles. No problems. That said, I have a friend with an
RV-8 whose aluminum pushrod failed after about 300 hours. Could have been
improperly tapped...could have been improperly installed (tension on the
pushrod when fully retracted)...I don't know the exact cause. He went to
steel after that. And I know several -6 drivers who went directly to steel
from the get-go.
Sure sounds like YMMV.
I personally have told myself that if one of my flap pushrods fail, I'll
convert to steel. The prospect of goring out that hole in the fuselage any
more, i.e. to accommodate the hex style, is unappealing (to me).

I'm fairly certain I didn't have to trim the hex pushrod for use on my RV-8.
The rod end bearing must have compensated for any length difference.
