Saying goodbye to 2013 and welcoming 2014

At first I had not properly understood the problem
as I replied with the following false solution :

2013 * 63336 = 127495368

The answer fulfills all the conditions except c) since
127495368 is not a palindrome but a mere ninedigital.
The multiplier is palindromic instead of the result.
It remains a beautiful equation though and a very unique one also.

One correct result was posted to me soon after. It is

2013 * 33409994526252 = 67254318981345276

In the past I dealt with a closely related problem namely
find the smallest multiplier of a number so that the result
is a palindrome. Please refer to:

http://www.worldofnumbers.com/won36.htm

http://www.worldofnumbers.com/won96.htm

The multiplication result in our case differs from the above links because
more conditions are involved rather than only being palindromic.
It needs also to be zeroless pandigital with all digits from 1 to 9
appearing at least once. That is the extra level of difficulty.
Therefore the palindrome is not necessarily the smallest palindrome
that is a multiple of 2013 (it is in fact 28182 or 2013 * 14).

Have you by any chance also the solution for next year's multiplicand 2014 ?

Several extra solutions were submitted afterwards
and a few solutions if 2013 is changed by 2014.

In the s^tyle of B.S. Rangaswamy let me say goodbye to
{ 2¹⁰ + 3⁶ + 2⁸ + 2² } and also
[ 5*400 + 9 + 4 ] or [ 2*900 + 21*9 + 6*4 ]

and welcoming
{ 2¹⁰ + 3⁶ + 2⁷ + 3⁴ + 2⁵ + 2⁴ + 2² } or
{ 2¹⁰ + 3⁶ + 3⁵ + 2*3² } and also
