    how do you refer to a piece of threaded metal which isn't a bolt? anyway, i need to replace the threaded pieces which you screw the wing nuts onto to hold the air cleaner box down. what size are these and how do you purchase this sort of thing? will i need to get a long strip and then cut it to whatever size i want? mine are stripped and so my air cleaner box rattles around and gets to where it has the opening facing the firewall, which can't be good for power. :o

    Threaded Rod or simply a Stud, depending on how its made. A stud is usually short and of a stronger material. Threaded rod comes in long pieces you can cut to length. You can get threaded rod at any hardware store.

    For an air cleaner threaded rod should be just fine, should be 1/4" x 20 tpi

    1/4-20 UNC to be exact ;) However it could be metric too? Most of the 6.2L uses metric bolts.

    i'm pretty sure the air cleaner studs are metric bottoms, and the uppers are american. I've tried screwin' around with rods and they didn't seem to work. (My upper threads were 'tarded up too)/ But i ended up using a bungie cord from the master cylinder over to the AC tubes out of the heater box for a temporarily long fix. Pins it down pretty good for the time being.

    Could be M6 into the intake then. The wing nuts I have on the topside are 1/4-20 though...

    If 1/4-20 won't quite start in those threads it'd be M6, if it pretty much drops into the threads it may be M8. 1/4" = 6.35mm

    You could run some M6 threaded rod and metric wing nuts...

    loose nuts!..

    My 6.2 loves to vibrate the air cleaner nuts off!--I lost both of the crap plastic wingnuts,and could only find metric 6mm ones in hex style,not wingnuts!..I had to slather RTV over them to keep them from loosening--I didn't use locktite,because I didn't want the stud coming out of the intake,rather than the nuts unscrewing..

    I have to find a "snorkle" tube, that goes from the air cleaner housing to the radiator support--it moans like a bull moose in heat at 30-35 mph without it!..I have some sort of "turbo" mufflers the previous owner put on,and my truck is pretty throaty at low rpms..but most of the noise is from the intake!.

    I think a junkyard would be the easiest place to find "new" air cleaner studs that will fit the first time,with no dicking around..:crazy:

    Actually, do you want a pair of stock studs? I have some extras you can have for the cost of shipping.
