My bolts are in pretty bad shape, looks like they have been cut down from unoriginal longer bolts. Some aren't fitting, even with the bumper off.
I am going to lightly tap the nuts and wanto get replacement bolts/rubber biscuit spacers. Are the 8.8 class m8 x 40mm bolts from the hardware store good enough for temporary use while I order the correct 10.9 class ones? the ones inside it now are 9.8. example of correct OEM: https://www.justkampers.com/n0103404-m8-x-4...rious-uses.html Temporary option: https://www.homedepot.ca/product/paulin-m8-...ated/1000135048 |

Factory bolts were 8.8 and plenty strong.

Some people use threaded studs to make hanging the bumper easier.

Some people use threaded studs to make hanging the bumper easier. But then they miss out on the fun of single-handed supporting a bumper in place while trying to get a bolt on each side started. (IMG:style_emoticons/default/headbang.gif) |

(IMG:style_emoticons/default/headbang.gif) Actually not to hard if you can find a large cardboard box to sit it on. Also works well for removing. |

Those bolts pictured above should sue for severe abuse. I guess some folks need help. |

Threaded studs are the only way to go!

Threaded studs are the only way to go! (IMG:style_emoticons/default/agree.gif) At least for the top two. I cut screwdriver slots in the studs, then switch them out for bolts after the bumpers are hung. |
