How to mount shocks on 14bff that angle inside the frame rails??

[85mudblazin]

i have seen them before but I forgot what they are called, they mount to the axle them angle up in between the frame rails where they are mounted on a crossmember type thing, but how do you mount the shock to the axle tube so that it can still flex??
Thanks

an easy is way is to use c channel, drill a hole, put a bolt through it and weld it there. it fits on the tube nicly.
