2. Right and left hubs.
3. Right and left axles with CV joints.
4. Right and left brake rotors.
5. Right and left brake calipers with rubber flex brake line.

8. All the bolts necessary to assemble the rear suspension. We recommend using ½-20 N.F. grade 8 quality bolts in all suspension related fastenings.
1. 4 bolts, ½-20 N.F. grade 8 x 1 ½ inches long.Modifications necessary to the Rear Suspension
2. 2 bolts, ½-20 N.F. grade 8 x 2 inches long.
3. 2 bolts, ½-20 N.F. grade 8 x 2 ½ inches long.
4. 4 bolts, ½-20 N.F. grade 8 x 3 inches long.
5. 8 bolts, ½-20 N.F. grade 8 x 3 ¼ inches long.
6. 4 bolts, ½-20 N.F. grade 8 x 3 ½ inches long.
7. 20 nuts, ½-20 high grade.
8. 20 lock washers.
9. 1 tube of locktite thread cement.
1. On each rear brake caliper ther is a cassted on tit which extends forward on the piston cylinder body that needs to be removed. You can use a hacksaw or grinder to remove these tits.
2. The long axle needs to be shortened 3 ¾ inches.
a) The axle can be cut in the center and remove 3 ¾ inches. Then use a sleeve over the axles and join them together by welding.Assembly and Installation of the Rear Suspension
b) Or, you can purchase and axle with this modification complete through Manta Cars.
Bushing Installation
Tools Needed:
One piece of all thread stock ½-13 x 6" long.
½-13 nuts and large washers.Assembly
1. Install the all thread stock through the long bushing. Use a large washer against the teflon bushing backed up with a ½-13 nut.
2. Slide the all thread stock through the center of the bushing mount on the control arm. Make sure that the bushing rests squareky against the bushing holder tube.
3. On the other end of the all thread, slide on a washer and thread on a nut. Run the nut down snug. Use a lubricant like WD-40 or some 3 in 1 oil etc. on the bushing to make it slide easier.
4. Tighten the nut that rests against the control arm until the bushing bottoms out against the control arm bushing stop.
5. Repeat this procedure with all of the bushings until they are all installed.
6. After all of the bushings are installed, insert all of the steel center hole sleeves. The sleeves should extend all of the way through the bushing with enough sleeve extension on the bushing stop side to install the narrow bushing. The bushing stop on the bushing holder on the control arm should be sandwiched with teflon bushings so there won’t be any metal against metal.
7. The teflon bushings may have to be ground to the proper length to fit in the frame mounting points. Hold the upper control arms up to the frame mounts and measure the amount to be ground off. Make sure that when you grind the bushings, not to remove too much material too fast because you want a good snug fit. The lower control arm bushings will have to be ground as well. Grind them to fit snug in the u-shaped frame mounts. After all of the bushings are fitted, it’s time to install them to the chassis.
8. Install the ball joints in the two upper control arms. These ball joints are supplied with the kit. Install these ball joints from the top side of the A-arm and bolt on using the bolts supplied. These bolts are a grade 8 quality and the nuts are a special self locking nut.
9. The bushings on the lower control arms on the out board side need to be ground so the steering lock-out device can be installed between them snugly. The upper control arms attach to the suspension mounting points on the upper frame rail using 3 ¼" long ½-20 grade 8 bolts (2 bolts on each side). Use ½" flat washers and one lock washer under the nut.
10. Install the 1 ½" long ½-20 grade 8 bolts in the frame mounting hole in the u-shaped frame mounts for the lower control arms. With the bolts in place, install the u-shaped mounts to the inner lower control arm bushings using 3 ½" long ½-20 grade 8 bolts with flat washers and one lock washer under the nut. Snugly secure all of the brackets to all of the lower control arm bushings.
11. With all of the brackets snugly in place on the bushings, hold the lower control arm up to the chassis and install in the holes provided on the chassis.
Because all of the bushings were ground to fit the brackets separately, the holes’ center line may have been changed slightly. If the bolts don’t line up with the holes on the chassis, you may have to elongate the frame holes to accept the control arms. Back up the nuts with ½" flat washers and lock washers.
12. Install the steering lock-out brackets on the hub carriers. If the holes in the plates on the lock-out bracket don’t line up with the holes on the hub carriers, it may be necessary to file the edge of the hub carriers where they come in contact with the weld radius, between the plates on the lock-out assembly. Use 3" long ½-20 grade 8 bolts with washers and a lock washer under the nut.
13. If wheel adapters are being used, they need to be installed next. Wheel adapters are available from Manta Cars.
To install the wheel adapters, the hubs must be removed from the axles. Remove the axle nuts and washers and tap the axle out of the hub. Remove the bolts from the axle bearing retainer and pull the hub out of the hub carrier. Attach the wheel adapters to the hubs. Be sure and sandwich the brake rotor between the hub and adapter and reassemble the hub and axle assembly.14. With the axle, hubs and hub carriers all assembled, slide the in board end of the axles into the transaxle. The spring lock ring should lock the axles into place. Attach the lower control arm to the bottom of the hub carrier (steering lock-out device) using 3 ½" long ½-20 grade 8 bolts and large washers under the bolt head nest to the teflon bushing. Use locktite on the bolt threads to lock the bolts into place.
15. Attach the upper control arm ball joint to the top of the hub carrier where provided. Be sure and use the bolt supplied with the ball joint to lock the ball joint stud to the hub carrier.
16. Attach the brake calipers to the hub carriers. Be sure they are installed on the proper side. This can be determined easily. Be sure that the fluid bleeder is pointed up. Now attach the rubber flex brake line to complete the mounting.
17. Install the shocks to the shock mounts on the chassis with 2 ½" long ½-20 grade 8 bolts and use 2" long ½-20 grade 8 bolts on the lower control arm mount. It will be necessary to make spacers to space the shocks on the shock bolts before tightening. Use lock washer.
Small outside diameter ½" flat washers will work for spacers; just stack them up for the desired amount of spacing needed. Or one piece spacers can be made from a thin wall 1/2" inside diameter mild steel tubing.
