Those will be just fine Jeff.  A higher voltage rating on capacitors is OK, you just don't want to go lower.

Edit: I'm starting to restore the same 1204 chassis except mine is going into a 12-S-265 console cabinet. For those three capacitors, I ordered 10's @ 50-volt when I placed my order with mouser, but if the 160-volt caps would fit in the can, and I had them in stock, that's what I would have used. Most of the e-caps I have in that size are 450-volt so since I was ordering resistors to rebuild the candohm I ordered some lower voltage caps at the same time.
