Thanks Byron. Was just wondering when I read the B suffix in the guide.

I'm not rebuilding mine back to exactly factory original anyway. More like how I think the factory should have built them. Nothing radically altered.
The interior is same color. HQ seatsdone in as close as possible color to the original, but with light & dark brown houndstooth inserts. Suede doorlinings and hood lining. Same as factory color.
