anybody know what cars i can get a clutch pedal from to work easily in a 65 auto,
whats the common swap. diy procedure?
i have ideas i can try but im sure this must have been done many times before by auto-manual swap home brewers

this should work on most MUSTANGS i have done this on mk1 68-75 escorts in uk which a are a lot smaller.

use a mk1 mexico/rs/tc peddal box which mounts girling brake cylinders (land rover ,ford,reliant,) to the actual pedal box inside the car with a flex hose running to 1-2-3 small resevoirs  2 for brakes 1 for clutch (more later) using thios also allows use of a bias cable adjuster

austin 1100-1300 mg and riley variants of the u.s austin america use  a similar pedal boz that also has been used in mk1-2 escorts kit cars and 105e anglias

you can also buy this part new from various sources inc raldes (rally design) and other european classic ford  stores there is also universal kits available from race stores kit car stores and most likley even oval race stores in usa

this comes with use of a cable clutch OR hydraulic if you use 3 cylinders ( 2 for brakes 1 for clutch)
then you will need either a thrust bearing type slave cylinder aftermarket or some factory cars (vauxhall (gm) omegas and others. not sure of u.s varaints) or  jap bellhousing mount slave cylinders or others but yoiu may have to mix n match slave to master to get best feel (light/heavy)

i may be able to help with more info and sourcing etc if you need it just p.m me
