Honestly, I don't think you'll find any, I've certainly never seen any. I assume you're going for a new UK reg, hence the need for new parts. If you want to do this I think you have a couple of options:
- Spend the money and get one of the sorted solutions from Southern, wealdon etc. They will be proven, without issues and known to work.
- Get a set of new "aftermarket" alloy hubs from Rally Design / Tornado / GT Forte etc. There have been questions over these in the past and the geometry isn't great. Use these to register the car, then swap out for a used set of Granada castings as they are stronger, but retain the crap geometry.
- Go with the wildwood pro spindles or one of the other US solutions and have custom wishbones made to suit the altered geo.
That's my thoughts, others may think otherwise.
