I made some progress today... I have mounted the diff to the TVPs and worked out i need a 16.5cm Rear drive shaft made up...
I also cut a alloy plate which will act as my motor plate and will be bolted to the side of the TVPs...
This is how the motor plate may look with the motor attached to the plate...
_dv thanks for the advice, i will do that... i will get the dimensions of the diff for you tomorrow.
