Converting from 2wd to 4x4

[Billy_RS]

i thought there was a bit around the gear box tunnel to allow the 4x4 gearbox?

Maybe there is then? As I did it the other way round 2wd from 4x4.

Is it an Escos your converting back to 4x4 or a 2wd sierra that's going to 4x4?

If it's a. Escos it won't need tunnel mods as it was designed for 4x4, it's only when the shell was 2wd originally it will need modding.
