how about a diff lock for the box?
are these a common thing and could they be expensive?
thinking its maybe going to be easier to just make the saph 4x4

I do not know any thing about diff locking a 4x4 gearbox. I assume your granada gearbox is an auto then?
If you want to go down the 4x4 route you will need a XR4x4 sump, front diff, front drive shalft, front hubs and front prop at least.
