I thought customized jerseys where when you got your name and # on the back of a pro jersey. You just want a throwback/oldschool jersey it sounds like. Like if I got a Larry Bird jersey. You can try MLB.com they usually sell old ones otherwise go to a collectible store in the mall nearest to you they usually have 1000's to choose from, but they are not cheap, well over $150.
BTW you can go to
MLB.com Shop - Phillies: Jerseys and see where it says "your name here" on the Jersey, just put Kruk and his # back there if you want it, that is a cheap alternative. You can also choose what year Phillies uniform you want to put the name and # on too, so pick your year and you are all set. I think this pretty much solves your problem. here is the link:
MLB.com Shop - Philadelphia Phillies: Jerseys: Personalized Jerseys: Search for (It says choose your name or your favorite players name)
PS: Why get Phillies when you can get
