Rear end lift...Need some input

I have used cheap coil over setups on two A-bodies (one 440 4sp, one slant/auto). I still have them here. About $30 at O'Reilly's, but I suggest welding the upper bracket to the shock sleeve or it will slip. Obviously there are better solutions, but we weren't in a position to buy new springs at the time.
