the messures are : steering rack complet without the track rod joint 960 mm.
Between the rubber gaiters : 460 mm. The shaft that sticks out is 30 mm and 14 mm diameter. The shaft to put the track rods on are 12,6 mm diameter.Any other messures needed, please ask. I have no 308, so I cannot tell you if the messures are the same. Cost for a cooper rack : reconditioned 30 £ RHD, reconditioned 50 £ LHD, NEW RHD or LHD 62 £, sportrack RHD 140 £.

308 rack

 

so guys, thanks a lot, but what is the conclusion after you pictures ????

IS IT THE SAME OR NOT ????????????????????????????

let us know, thanks , vincent

 

Yes, follow up on this! FofUK says that the 308 rack is no longer available.

Probable other critical dimension: Dia and spacing of where mounting bushings/brackets go.

 

There's no way you can conclude this by looking at the pictures. You'll need the specifications of each, or else somebody's going to have to throw in the "Pounds" and give it go themselves.

Can you give us the messures of the 308 rack ?
Total length, length between the 2 rubber gaiters, size of shaft to put steering column on + diameter, and diameter of shaft where track rod joint fits.

From my steering rack rebuild thread...

"The piston length is 27 1/2"
the rack housing is 22 1/2" long
the rods are 8" each not including rod ends
and the end of the driver side rod housing to the steering pinion center point is 3 1/4"
The rack housing mount points are adjustable to a degree,
but are on 12" centers."

I hope this helps,
although it's seems to be a non issue to me as the only part internally that need replacing in most cases, the passenger side bushing, is not only inexpensive, but also available in abundance.

For Example, Norwoods.

 

I am struggling with this one, my logic for what it's worth says to me that a rack to move a fairly heavy car (308) with very large tyres v a smaal light car with relatively skinny tyes will not be the same somewhere. The internal pressures, if the 308 is anything like my Mondial must be massive compared to shifting a mini about.

Just a thought for consideration.

I am looking for a conversion to power steering on the mondial if anybody has an idea.

 

In addition to retro-fitting a Mondial t power steering rack system, there are some aftermarket powersteering racks available.

Usually Norwood's is the best to discuss things like this - they are really not bound by the usual Ferrari paradigms. They might could engineer some brackets to mount the pump - I think the actual Mondial t rack will almost bolt up.

If I'm right : 960 mm gives 960:25.4 = 37 4/5" result for cooper rack
The 308 rack housing is 22 1/2" + rods(2 X 8")16" = 38 1/2"
So the diffirence in length is neglectable.
Other cooperrack qualifications :
The length rack housing side to center steering pinion is only 40 mm
or 1 1/2".
Also the position of the steering pinion is not 90 ° to the rest of the rack.When I see the picture of a 308 rack, this is 90 °.

The mount points are about 300 mm ( 11 4/5" )from one other also adjustable for about 1". The same as a 308 rack.
The only thing that wurrys me is the diffirence in angle to the steering pinion.
Maybe this can be compensated by the lower joint of steering column. And also the hole where the steering pinion goes inside the car.
The only way is to prove it by experience. Someone with a 308 in rebuild can try to put an old cooper rack in place ot the original.
