If you have a battery backed up S-RAM that's pin compatible with a
normal 6264, such as the Hyundai HY6264ALP, it's as simple as matching
the pins on the chip to those in the socket. The only signal that
isn't available is the R/W line -- you'll have to bend up that pin and
connect it via a wire to somewhere else on the motherboard. R/W is
available all over the place, check the schematics.

For 6264 and rom socket pinouts, check my article on adding 16K SRAM
to the VIC-20 on my homepage.
