You can't do either of those, because neither 147.64.in-addr.arpa nor 
64.in-addr.arpa were delegated to you.  You would only be able to do 
that if you'd been assigned 64.147.0.0/16 or 64.0.0.0/8.

When a block between /16 and /24 is assigned to you, ARIN actually 
delegates each /24 separately to you, i.e. they've delegated 
0.147.64.in-addr.arpa, 1.147.64.in-addr.arpa, ..., 
31.147.64.in-addr.arpa to your nameservers.

If you want to delegate any of these /24's to your customers, you have 
two options:

1. Submit a REASSIGN-DETAILED or REALLOCATE template to ARIN for the 
block, including the customer's nameservers in the request.  They will 
then delegate those /24's to the customer's servers, shadowing the 
delegation for the /19.

2. Configure your servers as slave servers for the delegated subzones.
