All v8 xr-xe manuals are hydrolic not big issue just 1" hole were the clutch go though and two small where the master cyl bolts on.
have made a hydrolic pedal box from cable before just a matter of moving the pivot and bit of chopping and welding so if you cant find one let me know.
would sell you mine if didnt just get my xf started after 5+ years and didnt spend welll over $2500 on box/recon/shifter/11"clutch etc
also dont make my mistake and start without starter motor spacer thay dont like being ingaged at 3000rpm

and if you can toploader from xb or early can take more punishment
