pedal box for mk1

gday, wondering if anyone on here knows of anyone making a pedal box to suit my mk1 eski with mk2 front and rear brakes? not sure how they work but someone on here suggested it will cure my braking woes so im prepared to give it a go. i believe they eliminate the need for a booster??? i cant remember whos build it was but someone on here had his existing pedal box modified for use in his mk1, does this fella still do em'? any help appreciated
