Something like these Wilwood pieces might work: https://pitstopusa.com/i-23931013-wilwood-compact-remote-master-cylinder-inlet-adapter.html
If not, you may have to machine some hose adapters to mimic the fitting on the base of the stock reservoir(s) to connect to a remote reservoir like this https://www.amazon.com/17-2878-BRAKE-RESERVOIR-PLASTIC-67-up/dp/B004C3DV5C
A neat trick is to mount the reservoir somewhere in the line of sight, as your driving, behind a viewing slot in an access cover to keep an eye on the fluid level . Maybe include a small light to view it at night. Another option is to find an OEM remote reservoir that has a float switch that lights a warning light, when the fluid is too low.
Or, use something like this aftermarket unit: https://www.europaspares.com/2-chamber-brake-reservoir-with-fluid-level-switch.html
