I hope this helps.
The bolt spacings in the photo are, from left to right, centre to centre of the bolts.
157mm,155mm,158mm
I know that sounds odd but I measured them with vernier calipers ( real ones not digital or dial ) There may be a bit srink or stretch in the rubber but it fitted my 1973 bar without any stretching.
That part number is listed as fitting 240z 260z right hand drive.
