I didn’t know that there was a difference. Thanks Mike B. I then measured the original studs that I have and yup, they are 7.5 inches.

So,…I emailed several vendors and despite having studs listed under TRUCK parts, all of them said that they carried the 6 inch studs.
I’m not going to bother asking any of the tri five car sites because it appears they all use the same vendor (the giveaway is that the photos are identical).

I’m still on the hunt for the elusive 7.5 inch studs.
