technically it works to move the upper part to the back but it is more practical to have an adjustable lower arm and tention rod. the following image is of a custom made one. won't cost you loads to do something simmilar
as mentioned by the otherguys you should use the s13 ball joints for the steering. i m still on the process i've never driven it with the new setup so i cant tell you how will it be but judging from the distance between the ball joints it will be nearly the same even a little bit lighter since the distance is bigger.
scientific equation moment = force * distance
keeping the same moment / longer distance = smaller force
u already know what is the camber. caster is nearly the same thing at 90 degree. the lower pivot will be in front of the upper pivot this will help for more stress on the front wheels while turning.
mostly recomended to keep this between 5 to 7 degrees.
the id plate is placed on the fire wall. and u will have ur engine number and chasis number stambed on it. for each car the id plate is unique. u can buy a clear one but they r very rare.
