Re the pics above, I have started making the template for the 2nd part of the adapter, I had to find a normal level datum so used a spirit level on the mounts for the clutch slave as that sits level in the original car; this should make the engine sit at correct slant.

I sprayed around the bellhousing to get a rough shape, I will make the prototype template in 2 bits of 10mm ally to see how the spigot looks in the flywheel to ensure it doesn't go in too deep.

The wings on the first plate locate the oe bolt holes on the mk4 golf bellhousing, there will be 5 bolts in total and these will stop the 2 part adapter twisting, I will use all but 2 of the original oe bellhousing bolt holes and before making a run of adapters I will make sure the adapters trim down and look neater.
