I have an 05 LGT 4.11 Ring and Pinion that I think is good. Let me look at it this weekend and I'll let you know.

Edit: I'm not 100% sure, but I thought the SVX ran an R180 out back which means my 160mm ring and pinion wont work for you if that is the case. I could be wrong though as I haven't really looked into the SVX.
