Early Fox cars are listed on the same line from '79-'93, so all equipment from one to another can be used. "Model" refers to equipment from a different year than those listed on the same line. Therefore you can build, for instance, a '93 with a carb, Cologne gear box, and 6 3/4 in. differential, with 13 inch rims.

Going from an AS car to IT will require you to do the following: remove any cage bars that go thru the firewall; move the battery to the engine compartment; replace lights if removed; replace the 8.8 rear with the 7 1/2, or the 6 3/4, change the brakes to the smaller discs of the 4 cylinder car, which also had drum brakes in the rear. The aftermarket suspension parts in the rear can be used as long as the original upper arms remain. They can be make legal with the use of "air Bushings". Personally, I like the four link used by itself, for its lightness, and the quirks of the design can be minimalized with bushing selection. Doing this will allow you to market the aftermarket parts for extra cash. AND, you will lighten the chassis at the same time. Build the car to the lightest you can, scrutinizing every part for its usefullness, and its weight. Leave off any part that will not make the car go down the track faster.


Using a notch, 6 3.4 rear, Cologne box, light but safe cage, poly cell, 13 inch rims (stock car stuff is very light), and they clear the calipers, and removing all available extraneous weight, you can build a car under the minimum weight as listed...I've done it.


I'd be willing to answer any questions. Write me.
