Tubular Lower Control Arm Thread

Ok--Here is a question--Just brought the duster home to start pulling the motor to put in the STROKER,Car is a 70 Duster--Looking at my front suspension and the upper and lower control arms,There is a support for the shock mount looks pretty rigid,SO what you guy's are telling me if I go with a coil over lower control arm that baddart is selling here for the stock k-member I still have to reinforce the upper shock mount???? this support comes of the upper control mount and goes up to where the shock mounts???? Thanks Keep up the good work baddart!!!!!!! Steve
