6540 rom replacement

I'm looking for details how to adapt an EPROM to replace the 6540 rom in a PET 2001. I have found some information but not a detailed description of how it can be done.
Thanks
Tim

For the BASIC rom I needed the RAM/ROM expansion to replace it. Apparently there was problems with my emails getting through otherwise purchase using PayPal went well and kit was delivered to Canada within 2 weeks. I haven't had time to assemble and test it yet.
I still would like information for replacing the ROM only as I will likely try to do it anyway.
Thanks
