Ryan Weaver's 1969 Olds Cutlass S W31 Club Coupe

[DW31S]

Ryan can you please measure wheels and post oh a doing so. I've seen '69 W-31 cars that were "supposedly" original with different width rims. I don't know if the Canadian destination could be a factor. Soliciting opinions or comments on this. Please take a picture with ruler or tape measure showing the overall width. Thanks in advance.
On another note, my 4-speed guy says not to use synthetic gear lube in Muncies. Seems the oil is too slippery and won't cling to the rotating parts.
