did you also mean the bolts that hold the spring plate to the IRS 'A' arm? Those are M12x1.5

the spring plate to IRS arm bolts are M12 x 1.75 8.8 grade high tensile. also amke sure you use high tensile or hardened washers to get a decent Tension Bolt connnection over the slotted holes

Weird cos the threaded hole in the 'A' arm was M12x1.5 when I put new ones in?
