dixon bate tow hitch bolt sizes for a 1985 One Ten

Hi all ,
I have a 1985 Land Rover One Ten which has had the rear cross member replaced , problem is that the dixon bate tow hitch was not put back on and the bolts are all missing which attach it to the chassis .

Can anyone help with the sizes of bolts for
the 3 bolts which hold the angle piece in place to the rear cross member ( captive nuts ,
the 2 bolts which go through the arms which attach to the chassis legs and lastly
the 4 that hold it on to the chassis and through the angled piece on the rear cross member

I am sure I have seen a PDF workshop page showing this but for the life of me I cant find it now

If anyone can help I would be a very happy man

Thanks all for reading

the 2 large ones are std towing bolts. about 3" long IIRC but a measure of the crossmember width will confirm.
the 2 above are same length but M12's (19mm hex head) the 3 that go thru angle into crossmember are M10 x 40
the Chassis leg bolts are m10 x 120mm

AGAIN This is from memory but should be easy to confirm. with a tape measure in the morning.,

wicked Redhand thanks a lot

Towing bolts are m16 on mine 24mm head and through cross member.

Make sure you have the reinforced strip

The cross member were m10x1.5
