Sidecar set up question

I do not have all the information as my friend is going to go get the rig tomorrow. I do know it is a 1990 Harley FLHP motorcycle with what I think is a double wide California sidecar. What toe and lean should I start with. The sidecar is on but the guy says it is not set up properly and I need a starting point to dial it in after riding. I know on my HD rig I run 3/4 toe with about 1 degree lean out. Would it be any different on his rig?

When I see it I will post pictures. Any help will greatly be appreciated.
Thanks
Jeff
