(from Rick Larson, rick@adc.com)

(Editorial note: the template Rick mentions can be retrieved from the classic-mustangs archive. The file you want is named "lower.ps". This is a PostScript document, which will of course require a PostScript printer should you wish to actually print the template.)

Parts and Tools Required

1. Template
2. Jack, jackstands, lug wrench
3. 1/2" socket for shock absorbers
4. Spring compressor
5. 3/4" wrench for control-arm mounting nuts
6. 1/2" drill with a 17/32" bit plus smaller bits for starting holes
7. center punch

Instructions

1. Jack car, remove front wheels and front shock absorbers.
2. Compress spring and remove.
3. Support lower control arm and brake assembly on a jackstand.
4. Unbolt control arm bolts from the inside of the engine compartment. For '64 - 66 years, save aligment shims and remember their original location.
5. Move the upper control arm, rotor, ans spindle to one side. Support brake lines.
6. Bolt the template to the existing holes.
7. Mark new holes with a center punch.
8. Drill new holes. Start with a small bit, 1/4", and work up to 17/32".
9. Install upper control arms in new holes. For 1964-66, use the alignment shims in the same original positions. Remove an even thickness, about 1/8" to 1/4", of shims for each position to compensate for the increased positive camber.
10. Reassemble suspension.
11. Align front suspension to the following specifications:

Caster 2 degrees positive
Camber 0 to 1/2 degree negative
Toe-in 1/8"
