The Indy white 78 duro are oh so very soft, so unless you like the feeling of almost no bushing resistance, or are ultra lightweight (or both) they often feel a bit too soft, as per the number of people I know who have bought them from me through my shop, but most are in one or both of those two categories, so those bushings work really well for them.
Are you putting them in Indy trucks or other?
Not that it matters, because they work in any and all trucks I have put them in, which includes the main four, plus a few other smaller brands.
That said, Indy aftermarket bushings break in very easily and hold up well (unless you tighten them down too much), so if you are in the above groups, I think they would work really well for you.
I have even trimmed down the top of those white bushings for at least one person to use in trucks that had been worn down a lot, so needed a lower top to fit on the kingpin with the truck grinded to axle, and they still worked fine, could turn, held up and bounced back to the middle too.
