2 drop coils and alignment
1990 F150 2wd.
Recently I changed radius and pivot arm bushings and just added 2 drop coils. All starting linkage was replaced about 3 years ago.
When I take the truck to get the alignment done, should I have adjustable caster bushings with me or should they be able to get it in without?

They will change them and use the ones they need
You don't know which ones the guy will need yet
You could buy Ford ones and have them on the seat because he will most likely not have access to Ford ones that are made of good steel
The aftermarket ones sometimes crack and break during removal and you need new ones for each alignment usually
Your 1990 2 wheel drive cams are different than the 4x4 ones
Maybe just tell him you talked to an alignment guy who said to use the best cams they can
Basically, when you dropped the truck, you lost some positive camber
The camber is supposed to go with the ride height (adjust) and a particular ride height requires a particular camber set (number)
When you slam one, all of thet is out the window
So, he will give it about a half degree of camber and get the caster straight and set the toe
Those cams can rotate and he may not need any cams at all, just to move them around, maybe replace 1 of them
