I've never heard of any issues with the trac bar drop bracket and TRO. I cant really see where there would be any.
I have, but the last time I experienced it personally, it was on a '77, which has the longer bracket from the factory. And in this case, no drop bracket was used and the GM TRO setup hit the
STOCK bracket.
the f150 nuckles tierod location is the same as the bronco drum nuckle location.
Like others, I thought mine was just a bit lower than the original EB too, when I first put them on. Unfortunately though, I didn't measure them to compare. They just looked just slightly (certainly not 3" though) lower.
Addicted, I just measured my current knuckles ('75 F150, according the the junkyard) and the top of the steering arm sits exactly 1.125" below the bottom edge of the trackbar mount bolt (the bolt, not the nut). Which means, in my case at least, the tie-rod would definitely be in the same plane as the bolt with a TRO setup.
Which also means, that even if the truck knuckles
are lower, it's not enough to compensate for a TRO.
So whether or not the upper trackbar mount would ever be an issue, the lower mount would still be something to be concerned with.
