That rear hook probably be ok but it will get ripped off the chassis when you get snatched out of a mud hole by a V8 landcrusier :oops: no very serious now IT WILL RIP OFF with a big pull I wouldnt snatch any Mu using it! BE WARNED !

the bolts must be 12mm or half inch at least 8.8 grade. The factory points are no good. Daisy knows. Hes still searching for his hook and the piece of chassis it was attached to.
Even 12mm bolts bend. Ive found one set of mine bent once and replaced all of them before the next time I went out. A standard Cookes snatch strap has a rated breaking load of 8000kg. Only one hook was tested and that might of been stronger than average. Thats not much of a safety margin

That's why I'm using grade 10 bolts at 12inch size. Will be mounted to new bumper which is 10mm thick on top. It is basically channel iron. Decent thick steel to mount the winch to.

Sounds Good. How are you mounting it to the chassis
Dont forget the rear. Even if you never get pulled backwards you may have to pull someone else forwards.

If your in a club check with your saftey officer. Most clubs only allow grade 8.8 I don't know why but grade 10 is sometimes not allowed.

Might want to check the rules for making bumpers When I made mine I used 6mm channel for the main part and mounting plates I was told that you are only allowed 8mm max

For a vehicle without airbags the only real rules that the front face is at least 50mm (it actualy says 50mm diameter tube. Not sure how that applies to square) and that there are no pedestrian traps.
Much better the pedestrian bounces off and goes under the truck rather than getting caught and dragged along.
They can get funny about a shroud over the winch but mine is similar to yours and never a problem. If it becomes a problem I will tie a potato sack over the winch

The number of bullbars on imported trucks I see that have a 6 to 8mm flat upright bar supporting the horizontal bars. Get too close to that at 50kph and it will act like a sharp axe. Still must of been complied when it landed and gets wofs

All sharp corners will be gone once done. I have some tubing for the sides to round it off. Using factory mount position and looking for a suitable secondary position off the chassis. I haven't quite found that yet. Will also put some flat plate to protect the underside.
