i built and raced a '72 mustang a few years ago. it was one of the best cars that i've had. the rear frame rails will need some reinforcement though. they are thin and real weak in the curve over the rearend. you'll need to add some weight to the rear as well.

1/4 mile medium banked and 3/8 mile medium banked. i used a 1050 lb. spring in the RF, a 1000 lb. in the LF, stock rear leafs with a 1" lowering block in the LR and a 2" lowering block in the RR. you'll need to add weight to the rear. i liked about 48-50% on the rear. a panhard bar is nice if your track allows it. try about 12 degrees of pinion angle. this should be a good place to start.

Hey thanks man thats great. What motor did you run? 301 or 351? I heard it was hard to get parts for the car. See I am thinking of buying a 1971 Mustang with a nice cage, good body (it's a fastback), with a good 9" rear end. For $250! The only problem is that it has no floor pan or fire wall, no Eng. or Tran. Really it has nopthing but tires, rims, a frame body and cage! Do you think I should buy it? How much would the rear end be worth?

i ran it with a 302 and a 351W.....won races with both engines at both tracks. it's worth $250 if it's not too bent up.

granadas, early mustangs, mavericks and their mercury counterparts use basically the same front suspension. 71-73 mustangs/cougars have the power steering in the box(this is good) and the others have a power assist slave cylinder(this is bad). use the granada type spindles, brakes and control arms. inner tie rod ends and other steering parts will have to be for a mustang/cougar. suspension parts are readily available at salvages and parts stores. the granada upper control arm is better too as it has a better inner bushing.

re-drill the upper control arm mounting holes in the shock tower 1" lower than the factory. this is an old shelby trick that will improve handling. you may have to trim out some of the re-inforcement of the inner shock tower to clear the larger granada inner bushing in it's new location.

rico, the reason you want a panhard bar on a leaf car is..........when you "set" the car in the corner, the rear shackles and bushings will allow some side to side movement of the rear end. this movement will sometimes cause the car to lose its "set" in the corner, especially if the track is rough, making it more difficult to drive. with a panhard bar, the car takes a "set" and keeps it. the old shelby's came with panhard bars from the factory.

i ran my mustang for 1 season in factory stock without the panhard bar and the rear shackles were bent sideways from the continous side load. the next season, i ran the car in outlaw stock with the panhard bar and leaf sliders. it performed much better.

it's also nice to have as a tuning tool.

Hey outlaw thanks for your help, I bought the car. I was wondering if you used the sway bar, I have heard of people not useing it? Oh also I was wondering if you had any parts from your old car that u never got rid of. Well thanks again!

i sold all the parts with the car. i didn't use the sway bar on that car, but i'm thinking of putting one on my '89 GT next season so i can run a softer spring on the RF. you can preload the sway bar to force the LF spring to do some of the work of the RF spring.
