Yes brother, it was very tempting, but actually the steering rack and main gadree is both of different designs of N16 and to fit them in B13, you need a lot of improvization :). The colour of B13 will remain the same Granite Grey, my first vehicle, my first B13 was also in this color, @ser_gtr also has same color B13, and yes, this one too. This colour is so killing in this B13 and body parts for this are very hard to find, though I have always come up with a solution to find its body parts in the same colour everytime :).
Thanks for the wishes, obliged.
