#1 ZF 8HP 70 box swap

Post by Fspp369 » Sun May 17, 2026 4:54 pm

Hello all,
I’m thinking of changing my 4sp with overdrive gbox,for a ZF8HP70.
I know that there are quite a few bits I’ve either got to fabricate or buy but I wonder if anyone has done this conversion here in the club.
The car is a V12 HE OTS currently in big pieces !!!.,
Any information about this subject is most welcome.
Peter.

I’m going for it with the ZF I’m planning to make the tunnel variation by removing the current tunnel down to the floor and from the bulkhead etc. would anyone be interested in the new tunnel fabrication as a set of pics or videos? Th box is quite large so the body G/B distance is my greatest concern.
I’d like to make a sort of “duplicate of the box” that I can haul it in and out all the time..any suggestions as to the material to make the “duplicate “.
Lastly, when it comes to prop shafts there are a few options. Any thoughts.
Several companies make quite a few bits but they’re all a bit of a compromise with regard to the body.
I’m tempted but maybe looking forward to the challenge when time is not too much of a worry.

If your intent is to make a large part of the gearbox covering removable, keep in mind that is a structural part of the car and design accordingly.
