To answer your questions, first let me explain the setup and its requirements. To use the gmt800-900 brake pkg a appropriate knuckle/spindle has to be used, on a 4wd its as simple as tossing in a new knuckle, on a 2wd not so. The balljoint orientation is different than any 800-900 platform, so a balljoint from one of those applications must be retrofitted to the 400 lca. Now the upper arm problem, no 800-900 applications fit either. I thought I had found one but it was way to short, so I used a LD2500 2wd arm. But still it was to short, I thought about cutting it and sleeving it to get the appropriate length, but the balljoint would have been at such an angle, I was afraid it would fracture and get me or somebody killed, especially the way I drive, also I didn't like the idea of a hacked up contol arm. So that got me thinking, if the arm was mounted out further my problems would be solved. I didn't want to have to make drastic changes so after some measuring I determined that moving the brackets out .5 inch and down .25 inch I should have enough to get good camber, after doing said modifications and installing the spring, it was necessary to also modify the spring, so I cut one coil off the bottom. After completing both sides, it looks great, I installed the engine to get some weight on the front and it appears I have 0* camber at full adjustment, and once more weight is added I should have even more adjustment.
