If running a non-stock clutch, having the firewall adjuster (along with ditching the flimsy stock quadrant/adjusting mechanism for an aluminum quadrant) is generally recommended.
So yeah, I'd go ahead with the minor modifications needed to use a stock cable with the adjuster. If you need any additional direction on this, look up the firewall adjuster install instructions on MaximumMotorsports site, it's pretty detailed about what exactly needs to be done.
