FYI I have a Marpet style MMU+Shifter SIMM adaptor upgrade in my 520ST like this:

I have to say, it's a snug fit, but was the only way to get the machine working easily, because there were so many issues with the onboard RAM.

The upgrade exxos posted a link to is the much more modern equivalent of the Marpet, so I'd recommend you go for that.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...
