    With the rear mark in place, take the shackle notch plate and place itagainst the frame with the rear of the notch plate (the end that doesn'thave an incline) right at the second mark we made. Once the plate is inposition, trace the outline of the plate.

    With the front pocket, rear notch plate, and shackle hanger tacked in,measure everything once more to make sure it is all is squared up. Itwould be a good idea to make reference points showing exactly where youmeasured from, that way when it comes time to do the other side, youknow exactly where to measure from and both sides will line up. If allthe measuring "measures" up, go ahead and weld everything into place.

    The TCI kit comes with new leaf springs, so there's no need to botherwith the old ones. With everything all welded up, install the leafsprings. The front of the spring has the pressed-in bushings; as for therear, place the busing in the eyes and slide the 5/8-inch sleeve intothe bushings. In the rear, install one end of the shackle to the mountand the other end to the spring. The fronts use a bolt that slidesthrough the OEM 1 1/4-inch hole, and the new spring pocket hole to mountthe leaf spring.

    Remember when we said we're tossing the old rearend? Here's why: abrand-new Moser Ford 9-inch with GM flanges. The Moser 9-inch Fordhousings are made with new heavy-duty housing cores, seamless steeltubing (3-inch O.D., 1/4-inch wall), new brackets, new housing ends, andnew bushings. All of the Moser 9-inch bolt-in housing and axle packagesinclude a new housing, Custom Alloy axles (28-, 31-, 33-, or35-spline--we went with 31-spline), ball bearings, up to 1/2-inch studsand heavy duty retainer plates. This package is designed specificallyfor Tri-Five Chevys and we figured this would be the perfect rear end toget our '57 up to modern-day performance and drivability, even if it isa Ford. Another cool thing we found out while doing this story is thatMoser can custom-build the axle length. Meaning exactly what? Let's sayyou want to shed 2 inches on each side of the axle and mini-tub the car;all it takes is a call to Moser. In the end, that means that since theleaves have been moved in 3 inches, thanks to TCI, and the axle has beenshrunk, with the addition of a mini-tub, you could put some seriouslywide rubber out back. See we here at Super Chevy have open minds...most ofthe time.

    Along with the new Moser 9-inch, we ditched the drums and went with aTCI rear disc kit. TCI offers several for Tri-Fives, but we wantedsomething that would suit everyday driving, not the turns of LagunaSeca. The basic kit from TCI uses GM 12x0.810-inch rotors with aninternal e-brake, which we got from Wilwood Disc Brakes and GM calipers.TCI builds its own bracket in order for the kit to bolt up. However, foreverything to work, we also had to get the proper axle flanges fromWilwood, which are the Chevy Special flanges. The basic TCI setup isnothin' fancy, but they do look and perform better than drums, which isexactly what we were looking for.

    With the rear in place, the shock mount and shocks can be installed. Bymeasuring 18 3/8 inches back from the front of the leaf-spring eye, thentransferring that mark to the top of the inside of the frame, the shockmount brackets can be installed to the frame. Do this on the other sideof the frame, as well.
