RV-4 Tank Removal
Patrick,
The -4 tank is a different from a -6, etc. All the screws countersink's are all dimpled, none are machine -countersunk. And, this is true for both rows of screws.
So, on my -4 I had to make wooden wedges from Pine which are placed 6" or so apart to peel the tank skin out of the dimples and then pull the tank off.
