We have a friend who is building a '67 Fairlane restomod. He has decidedthe original 8-inch axle isn't going to cut it with the larger engine hehas planned.
He wants a 9-inch axle, but he doesn't have any parts to build one. Hecould comb the boneyards looking for a complete Ford axle with a nodulariron gear case, but the chances of finding one are slim. Evengarden-variety axle housings with the gray-iron cases have becomescarce. Used to be you had to go with a high-dollar aftermarket case andeither a junkyard or custom-made housing if you wanted the strength andreliability that the big Ford axle offers. However, with theintroduction of the new Currie 9-Plus line of axle components, it's nowpossible to build a complete Ford 9-inch axle, using all Currie parts.One of the best things about 9-Plus parts is the gear carrier, which issuperior in strength to either the Ford gray-iron or nodular-iron cases.When compared with a stock Ford part, the Currie gear case is reinforcedwith additional webbing in crucial areas.
