turboaz Posted October 24, 2010 Report Share Posted October 24, 2010 I'm looking to ditch my powermasterIII and was wondering if a 93 Z34 lumina booster will work if I switch out the firewall plate. Also need to swap the battery tray. Thanks, Paul. 480-221-9572 Quote Link to comment Share on other sites More sharing options...
