On the Kadet I took a 1" x 3" 1/4" ply and put one in front of bulkhead 2 and one behind it. I used 5 minute epoxy too to make it really strong instead of CA. This pretty much puts the landing gear dead on the centerline, or slightly forward of the LE.   I then just tapped into the plywood and use 1/4-20 plastic bolts.
