Kinda new over here read through most of the posts goood info.My question for you guys is what do You use for your steering coupler with your upgraded boxes?The box in my challenger is shot and I can stand it no longer.So I shipped mine to firm feel today but forgot to ask Mr. Ross about the coupler.Is there an upgrade?Or is a properly rebuilt stocker ok?This is an ex drag car being built back to a driver that will have excellent handling.Thanks guys
