I'm restoring a much abused moke here in Kenya. The rear subframe was too far gone so I found a (hydrolasti) replacement. After replacing the complete floor, side panels and heelboard, and placing them meticulously, I find the replacement subframe mounting points don't match up. The distance from the subframe front 'face' and the centre of the rear trunnion 'threaded pin' is 622mm and that pin is around 17mm rearward of where it should be.
Have I got an odd subframe from a different vehicle? Could someone kindly measure theirs and let me know?
Someone at wood & picket answered my query on the bay of e saying their were at least three sizes, but hasn't enlarged on this.
I don't want to start cutting up either the car or the subframe unnecessarily, so any help would be much appreciated.

All Mini subframe use the same body mounting holes. Moles I believe used only longer radius arms later on.

 

I would post up a picture of the frame. Use Imgur to host it.

Can you compare the old subframe with the new one?

Check you have the Rear Trunnions are on the right way around, the big hole for the rubber is off set in them, the 'tall' side of them goes towards the back of the car.  Even with this in mind, 17 mm seems a lot. The mounting points for all subframes as best I know from start to finish of production were all the same.

 

From the Heel Board face (that the subframe mounts up to) the the centre of the front hole of the rear Mount should be 599 mm +/- 3 mm.

 

With all the body repairs that have been done, it is of course possible that some bits have moved, however if the rear Tray has been untouched and the Heel Board is still close to 900 to the tray, then it should line up.

Having spent the past few days fighting a rear subframe for fitment. Stay at it, especially with new rubbers they look like they're really off but it will fit.

17mm is a fair distance to move but it may just be the rubber mountings as mentioned above.

 

Do you have any pictures of it to show the front mountings and the issue with the rear mountings?

 

As far as i'm aware all rear subframes across all years have the same mounting point dimensions, i've fitted swapped subframes from 1980's and 1960's cars and swapped hydrolastic for dry without any issues.

Not really. The forum limits the size and type of attachment you can add.

This is another way of up-loading photos, but just note the size limits - Max 2MB per photo.

 

If your photos are bigger than this, there's a few on-line photo size reducers.

Thanks Gaspen for this suggestion.

Here's a couple more. Spider says, and thankyou Spider, that the distance from the heelboard to the nearest rear mounting hole is 599mm + or - 3mm. Mine is pretty much spot on, although I welded up the holes as they were oval from movement. I know where they should be and I'll re drill them.
Which brings me back to the subframe being oversize. There's no sign that it's been altered but I wonder if it's from a different vehicle, a 1300 or a special vehicle. Could someone kindly measure one in the same way I've done?

In response to greenwheels, the old subframe was badly damaged, bent even, with bits of angle iron welded to it, so I disposed of it at an early stage.
