Thanks for the helpful comments
UPDATE
1 Happy with the drive shafts looks like there was no problem at all.
2 Cut a bit off the long lower sus bolts they now clear the wheel rim.
3 Dummy struts in progress
4 Just to clear up the confusion CP10 s are fully welded in place with the nearside one upside down.It will be a nightmare to grind out or it could be re drilled and the holes closed upwith weld. I reason it may be a lot easier to weld the the diff mount plates to the CPs unless there was a reason why I shouldn't. The diff mount brackets are also fully welded as per spec
Cheers
Adrian PS Any thoughts on welding up diff mounts as in 4?
