The later kits come with some wood locators. I used a strip of Velcro 3/4” wide about 12” long parallel with the top face of the tank where it touches the fuselage side. The spar notch stops the tank moving forward/backwards, I did add a spot of silicon to remove any chafing in the tank arch. The Velcro stops the tank moving up, I’ve tried some fairly hard negative snaps and nothing moves.
The CARF wood parts are designed to go on the top section under the canopy split line lip.
