What is the best position to drill a hole in the right rear sill end panel (16-2021) to inspect the right sill?
-- need to see past the front and rear inner sill stiffeners (16-2020 and 16-2019)
-- can you please provide measurements
Wish to clean out, spray rust preventer and waxoyl
I have only one inspection 7/8" hole in the right inter sill 16-2015RH behind the cross member 16-2025
What size hole to do you recommend?
What did you use to plug the hole?
Do you have any other suggestions?
I have a camera with a 17MM head or 0.67 inches
John
