Very expensive from what I've heard.
Why not try James martin on this forum - It's his business. I've used him for a gearbox recon and very pleased.
He's in Linconshire - PM him I'm sure he'll sort you out.
I had a recon LT77 from them, tis a good box but second can be a pain sometimes. Good service but yes, aren't the cheapest - but again I have heard they offer very good service even when problems arise out-of-warranty.
