To all the very knowledgeable members out there - need a little guidance:

1982 300 TD
The air filter casing is rattling on it's mounts - I checked it out and at least one, if not 2 mounts have lost the nut on the underside. Can anybody tell me what size nut these are and what else I will need (lock washers?) to secure them. Also - the air filter mount nut just over the turbo might have come off too, I am not sure. But assuming it has - how the hell do I get at it? I can barely reach in there to ascertain if the nut is missing.

Thanks in advance.
