[s-cars] EM replacement question

[jimk at spotgraphicsinc.com]

Hello,
If I were to take my RS2 EM off of my car and replace it with the stock
piece (in order to move the RS2 stuff to the new car) would I have to
remove and replace the studs as well?  Obviously some are shorter but
are they still long enough to work with the stock piece or must the
studs always be changed anyway during a swap?
Thanks
Jim K.
