not sure if this is any help funky? my abs proportion valve had 4 lines - both left & right rears feeding 'from' the abs unit into then out to rear wheels, my abs master cylinder had only two lines feeding 'to' abs unit, whereas the non abs has 4 lines from master cylinder

my rs didn't have abs, the gt i removed the abs system,
you will need a master cylinder & portion valve from a non abs vehicle & the two short lines from master cyclinder to portion valve also (for the rear brakes), abs has only two side ports from the master cylinder, whereas non abs has four.
i removed all the sensors from the hubs & plugged the holes in front wheel arches with blanking gromets found on the non abs versions, same with the rear lines under the rear seat on both sides,
The Two Front wheel lines need to be shortened, & because they are coated this makes it kind of a pain but with the right tools it can be done, On the other hand you can use a 3/16 pipe bending plier & bend to suit to plumb into the two side ports of the master cylinder.
The two bottom ports from the master cylinder run to the portion valve & run to the two (rear brake) lines running from beside the booster through the firewall beside throttle cable
also remove the little bulb that twists from behind the speedo cluster, this is the abs light & check it's the right one as i removed the intercooler one, so then i had to do that over again
remove the fuses from the fuse box, & that's about job done once system bleed.
