Drive flange bolt size

I've just changed my rear half shafts and drive flanges, as they were all worn, full of play, and causing a big clunk when pulling off. The play has gone, the clunk has almost gone (A frame ball joint is the next task)

While i was taking it apart, I noticed the bolts for the drive flanges were 13mm head and fairly old and knackered on one side, and 17mm head and fairly new looking on the other side. I was naive in thinking I'd get new ones with the HD flanges I bought from Paddocks, so had to put back what was already there.

I'll be revisiting the back axle soon as one side was full of ****e and I don't trust the wheel bearings on the strength of that, so just wondering, which bolts are the correct ones, and does anyone have an idea on part numbers for the bolts? That way everything will be correct (ish) and I'll be happy (until the next big f*** up)

Thanks in advance

Forgot to add its a 1994 110 station wagon, with 24 spline rear axle and disc brakes it's ex AA and allegedly went via special vehicles

they are m10 bolt and should be hex headed as are 10.9 special bolts google bx110095m

They look like the 'good' ones with 17mm hex head on one side, so will order some of them with the bits and bobs for doing the bearings, suspected they might be something special and didn't want to use any old crap so thanks for letting me know on that one

dont over tighten them 50 lbsft is enough then can shear
