Trailing Arm bolts

Evening all, Got my new front axle fitted now and today I finished pulling the back axle off, all went ok until I went to remove the trailing arm to chassis bushes.

I've had to grind off the 3 bolts on each trailing arm/chassis bracket after destroying them with the impact gun, they are the ones that surround the main retaining nut and hold the bush in, does anyone know what size they are so I can get some new ones?

Thanks, Harry

there M8 x 25 if i remember right, I drilled mine out and put M10 x 25 stainless steel nuts and bolts

mine are M10

Thanks guys will pick some up this weekend
