Subframe color: BLUE Pitman arm bracket?

[Hodgepodge]

I know there have been a few threads on this and as I recall, the consensus was that early subframes were grey and the later ones were black, but I just came across something interesting.  I was pulling all the bushings from the front subframe of my '75 2002 in preparation for media blasting and powdercoating and found BRIGHT BLUE under the pitman arm bushings!   It does not look like a sleeve.   Can anyone tell me why this would be BLUE and if I should make sure this is protected during media blasting and powdercoating?     

 

Thanks in advance for your thoughts on the matter.

looks like the outer sleeve from one of these.

If its a bushing leave it in there when media blasting it will protect the sleeve and melt when its powder coated. The new bushing will fit nicely  after its removed

Well  thank you gentlemen!   I had a hunch it was a sleeve but it didn't look like it would come out easily.  I love the idea of just leaving it there through media and powdercoating. 

 

Thanks!
