Default 77-81

Did the 77-81 Bonnevilles have the 5x5 bolt pattern or were they the smaller 5x4.75 pattern?

Thanks in advance!

5 X 4.75"

Wheels from my 1970 Firebird fit on my 1981 Bonneville when I needed a spare in a pinch.

They had both, depending on the installed engine. Anything smaller than 350 got 11" front discs, a 7.5" rear and 5x4.75 pattern. 350's and up got 12" front discs, 8.5" rear and 5x5. Not quite sure about wagons, they might have always had 5x5.
