Pk forks in vbb

hi,can i put (sip) pk forks in my vbb but keep the original hub and drum brakes til i can afford the disc kit?

i have done this conversion, and it is NOT possible to use the VBB hub or any of the front brake components.  

 

You can use the PKXL2 or T5 drum brake components, but there is a small very critical part of the brake cam that is completely unavailable.  I spent several months and more money than you would expect trying to run a PK drum brake.  

Save your self a lot of time, money, and frustration any just buy the disk brake.  If you can't pay for it now, just wait until you can.
