@aleem
was great meeting up with you after so long, however i didn't get time to inspect your new purchse.
@haywire
is the PCD 4x130 or something else? if it is anythign else it is possible that hte bolts were not placed correctly (similar problem on my 1303 which is why i went back to 4x130). the off-centre rotation would lead to handling issues as well as causing your shock to overheat and fail quickly.
as for engine numebrs, the letter(s) before the number are more important and they can be decoded using the engine list i posted a few pages abck.
