    ^That looks like it would work.

    I found a pic on ebay of that AC Delco part (45G1004) and the stud looks to be 1-3/8" long.
    Trim the "nub" and you're good to go!

    I also found a NAPA part which looks identical... NAPA 14203

    Both of these appear to have a few more threads than some of the other ones I've seen.

    Okay what are you calling the nub. At the bottom?

    Yes... The bump on the bottom which fits into the spacer to prevent it from rotating around the stud.

    The "nub" on the Moog bumpers needs to be trimmed too so it fits the spacers.

    I went thru all this while looking for spacers for my car. The '70-'74 Z's used the 3/4" spacer & the '77 & later used spacers just over 1/2" (17/32"). Both styles are 2.5" long & 1" wide. In about 2012 bought the Moog 6606 snubbers from Rock Auto - made in USA btw. They all have the 1-3/8" stud; the little nub just barely needs to be rounded to fit the dimple hole. I agree with Twisted, the AC Delco looks to have the proper length of stud vs the current offering from Moog.

    Do you have to run the spacers or can them be removed.

    I have a 70 Z28 that is missing the spacer. I assume at some point in its life they were replaced and the long stud bumper could not be purchased so they were replaced with regular bumpers. I can't say that it will help with the ride but Im trying to get back to original state.
