I'm making a new part of the chassis in front of the engine mounts with a heavy duty winch bar and recovery point mounts and the ability to use an a-frame for towing
For all the bolt holes including a power steering box im using crush tubes but i'm wondering which method of attachment is satisfactory.
will (a) be fine or should i go to the extents of (c).
a. weld on fishplate then fillet weld to the crush tube
b. weld crush tube to rhs then a bigger hole in the fish plate to go over the weld and then weld again to the fish plate
c. weld fish plate to rhs then counter sink crush tube hole and then fillet weld the crush tube so it welds to both the fish plate and rhs
