Hello, apologies if this is stickied somewhere I couldn't locate, but I haven't had much luck with an exact answer. I'm attempting to remove front bumper (2010 GSR) and while my car is rust-free, the bumper bolts have not been so lucky. The bolts are all basically rusty mush...one of the two bolts that hold the bumper on near the front badge has already snapped. There is actually enough rust on some of these bolts that I can't even fit a 10mm around them anymore. Anyway, before I proceeded with trying to force/drill them all out, I wanted to have the right replacements on hand first. I've found that the ones under the car might be M6mmx1.0x20. I'm hoping someone would be able to confirm?

 

I am also looking for the size, please update if found

 

You mean these bolts?

 

I just checked and the two front bolts are M6X1.0 10mm and the underbody are M6X1.0 20mm. You could go longer on the front crash beam as there's space behind those holes.
