Plans called for aluminum stem pull rivets to attach the canopy and skirt to frame(canopy sandwiched between skirt and frame) but calls for the steel stem aluminum rivets (CSC4-4) to attach skirt o frame everywhere else.
Question is... What's the best action to take if csc4-4 rivets were used where the others were called out?
I know the clamping force is greater with steel stems but not sure if trying to drill out the wrong ones is worth the risk or not.
Does anyone have any advice on this?
Thanks!
