From that start, your imagination is your onlylimit. From drive train to paint scheme, you can style your bucketto match your personality.It is our goal to see you through this project and help youaccomplish the task of building the T bucket of your dreams.If you have any questions feel free to call of at 1-870-425-5900
Spirit IndustriesT-Bucket Instruction ManualPage 1Chassis BuildThe chassis is easily assembled in just a few hours.Before you begin building your kit, it’s best to lay out allof the parts and familiarize yourself with the pieces.NOTE: We recommend you pre-assembleyour chassis prior to prepping and painting.We recomend using Loc-Titeon all nut-bolt combinatins.Spirit’s grade 8 bolt kit are inlabled packages.
Spirit IndustriesT-Bucket Instruction ManualPage 2Frame PreparationSet the frame on jackstands and drill allnecessary holes.Holes to be drilled include 5/8”hole in front cross-member forthreaded rod (front frictionshocks), all thru-the-frame fittings,brake lines, wiring and groundstrap.NOTE: Thru-the-frame brake fittings require the holes to bedrilled in the upper 1/3 portion of the frame to preventinterference with the radius rod.Drill a 5/8” hole through thecenter of both ends of thefront crossmember.Then, slide the threadedrod through the crossmember and install thefriction shock componentsonto the rod.
Spirit IndustriesT-Bucket Instruction ManualPage 3Front Axle AssemblyBe sure to use jamb nuts when installing clevises and rod ends into radius rods1.)Assemble axle on the floor with spring, shackle assemblies, and radius rodsNOTE: When installing the shackle bolts into the shackle and spring make sure the nutsare towards the front of the car. This gives you maximum turning radius. After locknuts are tight cut off excess bolt flush to nut.When attaching the radius rods to the front axle,use longer bolts through the upper clevis. Thesebolts will also be used to attach the axle to thefriction shock.NOTE: We recommend 5 - 7 positive caster.Camber is preset into the axle.2.)After connecting the radius rods to the axle, attachthe other end of the radius rods to the mountingbrackets on the frame. Then lift the spring/axleassembly into the spring perch.Using the panhard bracket, sandwich thespring between the bracket and the perch, andbolt together.Attach the lower clevis to the rightfront radius rod to the axle using thebracket for the panhard rod.
Spirit IndustriesT-Bucket Instruction ManualBe sure to use jamb nuts when installing clevises and rod ends into radiusrods. Routinely check bolt tightness on all suspension parts.The connecting rod ends connect the friction shock to theaxle, using the long bolt in the upper radius rod clevis.Build front spindle/brake assemblies on the bench, then install on the axle.Inner race must be replaced withthe ones included in the kit.When assembling front hub assembly, makesure to use Loc-Tite on all nuts and bolts.Page 4

If so, use a brakecylinder hone until the king pin barely slides into boss.Kingpin / Spindle Assy.Make sure to face the flat spoton the king pin towards the setscrew in the axle, prior totightning the set screw.Be sure to place cup washer and felt washer onthe kingpin prior to installation. Apply grease tokingpin before installing into the spindle.Page 5
Spirit IndustriesT-Bucket Instruction ManualBe sure to use jamb nuts when installing clevises and rod ends into radiusrods. Routinely check bolt tightness on all suspension parts.When installing rear differential, firstbolt radius rods to brackets on rearend.With the differential on the floor atthe rear of the car, attach the otherend of each radius rod to thebrackets on frame.Use a floor jack to lift the differentialinto position and attach the shocks.Rear panhard rod attaches to both rearend and frame using 1/2” bolts and nuts. Werecommend using Loc-Tite on all nut & bolt combinations.Once the rearend is hung, the differential canbe centered by twisting the panhard rod.Page 6

Wheninstalling pedal, make sure you double nut it to keep iton and use grease on shaft.Proportioning Valve is used to adjustthe brakes so that the front brakes donot lock up before the rear brakes.Drill 13/64 hole and tap with 1/4 - 20NC, and use 2” bolt to hangproportionate valve.Optional Power Brake BoosterProportionate ValveBrake kit includes all necessaryfittings. Lines require cutting,and flaring tool is required toinstall fitings on lines.
Spirit IndustriesT-Bucket Instruction ManualPage 8BRAKE LINESRearthru-the-framesetupThis is just anexample of one wayto run brake lines.There is no realstandard. You cando a custom thruthe-frameinstallation if you’dlike.When running brake lines, you will need a tubing cutter and a flaring tool for the installation. Becareful not to “kink” the lines when making bends.Lines coming off the brake pressure switch will split with a “T” fitting to run toward [email protected] of the car. Install with c-clamps on transmission cross member, then runboth sides to front and connect to thru-the-frame fittings.Lines running to the rear will “T” at the thru-the-frame fitting on the line coming directly from themaster cylinder. Continue from “T” fitting around the back of the car, bending and clamping the lineto the frame. Connect to the thru-the-frame fitting on the rear passenger side of the car.Connect steel braided brake lines to wheel cylinders and thru-the-frame fittings on all four wheels.Rear Panhard Bracket“T” FittingSteel braided flex line for rear wheel.
Spirit IndustriesT-Bucket Instruction ManualVega Steering BoxThe Spirit frame is set up to use a Vega steeringbox. The steering box does NOT come standard withthe Stage 3kit, but a Vega steering box can bepurchased from Spirit, and includes the Grade 8 boltkit with all bolts and spacers. A straight pitman doesnot work with the Spirit/Vega setup. Spirit’s speciallydesigned pitman arm is available in paint or chrome.See the catalog, or call for pricing.The Vega steering box housing is rounded on theside that mounts to the welded frame bracket, so youmust use spacers between the housing and themounting bracket to get a good tight seat.After mounting the Vegasteering box , you will need toset the front-end alignment.Before connecting the steeringrod from the slingshot arm tothe steering box, rotate thepitman arm back and forth allthe to the front and then all theway to the back in order to findthe center of travel.Next, align the spindles/rotors topoint straight to the front as iftraveling in a straight line.Now, connect the steering rodfrom the slingshot arm to thesteering box.Minor adjustments may berequired after installing yoursteering wheel.NOTE: Set the toe-in to 1/8”Page 9
