289 vs 427 footbox

[CompClassics]

1) The foot boxes are riveted to the scuttle hoop.

2) There is more room to the right and left of the steering column.

3) throttle pedal is completely different, that's an easy one.

4) the pedal box assembly needs to be relocated.

5) the firewall sheet metal is different.

6) the floor pans are different.

7) the transmission tunnel is different, along with the removable panel to the front of it.

8) the hydraulic master cylinder hard lines may need to be replaced or altered.

9) steering shaft lengths may have to be altered.

10) diagonal braces may need to be altered and brackets added (steering column support.

11) different steering column supports will have to be sourced.

12) original details like the dead pedal and high / low beam switch should be added.

13) original details like the wiper motor assembly can be added.

14) passengers side foot box bracket / battery box needs to be added, supports the foot box.

15) depending on how your current exhaust headers are routed, new exhaust headers are needed.

As I had previously stated this is not an easy modification, especially when the car is already in a completed state. I replaced mine without removing the body but I had to make special brackets to attach the outside of the foot boxes to the chassis.
