Quick question that may be a stupid one...

Buying new Cragars and trying to figure out which lugs to get. Planned on getting the Cragar ones but the Mcgards appear to be better quality. However, the shank size, diameter, and washer size are slighly (ever so) different/smaller. My question is does it matter and will they work?

Cragar lugs have a shank length of .8 inches, diam of .684, and washer at 1.25 inch diam.

Mcgards are .746 inch shank length, .679 inch diam, and only 1.062 inch washer outside diam.

Here's the 2 I'm comparing...(open to other suggestions as well!)

Thanks for the help and sorry again if its a stupid question, just want to be sure and safe.

I think the Mcgards are a better quality but with the oblong holes in the Crager wheels (to fit 4 1/2", 4 3/4", 5" bolt patterns) I'd want the tightest nug nuts and washers I could get!!!
