Did some more investigation on B6 swap. First made a bracket to determine the position of chassis leg in relation to the existing IB5 gearbox. Rather crude, but enough for some conclusions and ideas...
You can notice the inlination: the engine is tilted to the rear in the engine bay.
And the outcome is here. It is remarkably close! The ST180 gearbox mount will need rasing by about a cm or so..
I guess I will need taking these studs out and replace them with slightly longer ones. They are studs?
Then it would just be a matter of making a subplate thick about a cm or so and sliding it beneath the mount. The other side is offset in relation to the puma one about a cm or so to the left (further away from the engine).
The holes are for the original puma mount that was bolted here previously
Now, this might be a problem
It is fouling my construction. If the chassis leg is more like capital letter I in cross section, that shouldn't be a problem.
If not, some cutting and welding will be required...
Also, there might be slight clearance issue with the cable bracket on the gearbox and the hose for heating the cabin
Fortunately, the big metal part at the back is bolted to the carrier and can be taken down and modified shoudl be needed. I would really like to see the fiesta hose as the engine water outlet is more or less the same....
