Hi all , I've done a web search to no avail , looked on the chassis drawings that I have in my workshop manual and there not even on there so thought I'd ask on here does anyone know or could measure off there own chassis were the front ARB mounts are situated please ?I've got the mounts ready to weld on and need to fit them sharpish as my chassis is going to work soon to be galved .
cheers Ian
