Hardware metric or standard?

[Warwagon]

Is the hardware on the 2004 CTD metric or standard. ? Trying to fix treads on spirng stack bolts. Tryed to move spacer to top of spring to lower rear end height.

if you are talking about the center pin in the leaf springs they are usually grade 1 or so so they bend and not break. I am not sure what Dodge uses I know they strip out without much effort. when I buy them they come in sizes of 5/16 or 3/8 or 7/16 etc but these are generic. in a pinch you can use a regular bolt and grind the corners off of the hex head to fit back into axle perch. I am sure if you order by your VIN# at the dealership you will get the correct ones. to determine if bolts are standard or metric and I am not sure if center pins will have this or not. lines in the head are SAE standard representing the grade of the bolt and when they have numbers they are metric to represent the grade of the bolt

i've got regular 1/2"NC bolts with the 3/4" hex head in the axle perch with no grinding. i can't remember the length though.
my stock bolts are scrap iron now
