There are several vectors that do not have any viral sequences upstream 
from the XhoI site you refer to. This still leaves approx. 2 kb of 
viral sequences which is sufficient for recombinantion. Our pBacPAK8 
& 9 vectors have even less viral sequences, approx. 1.3 kb, and still 
work very well. Changing XhoI to PstI should not be a problem.
