Can someone please tell me the bolt size and thread pitch of the top 4 bolts that hold a tow bar to the back face of the chassis on a Defender. I'm pretty sure that on late models there are captive nuts in the chassis.
I'm guessing the bolts are M12 but I need to confirm this along with the x pitch?? x length??

Cheers, Murray

Murray, If you can't get an answer here just take one to a nut and bolt place and they will be able to tell you.

G'day Dave,
I haven't got one, that's the problem. I just need to know what thread they are so I can supply them with the wheel carriers where there is no tow bar present. If I had one I would know what it is. :)

30mm M12*1.75 with a 18mm head came with the hayman reece setup I have.
I put 45mm M12*1.75 with a 19 mm head in the top two holes that support the spacer and bottom carrier support. The 30mm ones were only holding by a couple of threads.
Hope this helps.

You're a champ Tod,
Thanks for that. I was thinking about 40mm, but 45mm will do just fine. I was supplying 90mm bolts to go right through the chassis, not realising there were captive nuts in the newer models.
