Technical Speedway wishbones with the holes

I have a pair of wishbones with the holes drilled. Do these need to be sleeved?
Thanks

 

I would

 

I built a chassis for a customer using those and thought they are rather flimsy so, yes, I believe they should be sleeved.

 

Yes. Wish bones are only tubing so drilling holes in them does not make them stronger.
I bet installing sleeves makes them heavier than they were stock.
Weigh your bones (before and after) and let us know.
Put on your long sleeve shirt and start "sleeving".
