    Can anyone confirm that the M1028/M1008 were fitted with 1 1/2" rear spring shackle bushes please?

    I intend to replace all of my M1028's (military Chevy K30) bushes. Because they're so badly perished and I don't want to be off the road for any length of time, I would prefer to have the replacements on hand during the tear down.

    Without disassembling the rear spring shackle, I found a bush that projected more on the driver's side. If I measure what looks like a steel insert surrounding the bush in the spring eye, I get 1 1/2" and about the same for the perished rubber I can measure in the bottom of the shackle.

    Most stock Chevy rear shackle bushings from 73-91 were 1 1/2". I think some 1 tons had 1 3/4" bushings but I dont remember the specifics of which had them.
