Are you running the Deaver 5.5" coils? That is what I am running, but they are used as well. Initially they are 22" unsprung, mine were settled at 20". So they'e settled a good 2". I might not lose height if I switch to the plate, but I might at the same time. I am not sure.
Alignment shop says bent pitman arm and drivers side tierod. Does the pitman arm have to go all the way up to the box so no splines show? The splines coming out of the box look tapered like the pitman isn't supposed to go all the way?
