Bolt Patern & Offset for 68 Riv GS

[agenex]

I'm looking for the bolt patern and offset for a 68 Riv GS rim.

Will a 10" wide fit in there, and if so what offset will I need on the rim?

thanks in advance - you guys have been a big help for me.

5x5, 3.25" according to this thread (http://www.v8buick.com/showthread.php?t=141527).

i dunno about 10" wheels. i'm sure someone here does, tho.
if you get them on, post some pics and info!
good luck!:beer
