hello to all.. i am new to this list and a AACA member.. can anyone tell me how the front axle on my 1930 Ford Model A roadster i am restoring is to be oriented... the top and bottom are obvious to me but the front and back are not and i dont want to install it backwards... also the large wish bone which attaches to the perch mountings and center of the vehicle has an up and down and i am not certain of it's orientation either(i should have taken pictures before i disassembled it but didn't....) thanks so much ...rocky d
