That's what I did. I converted my 1956 TR3 from front drums to 1968 TR4A
Disks. I used the caliper mounting brackets, calipers, rotors, and dust
plate/backing shields. I also scavenged all the necessary bolts from the
TR4A. It all bolted up to the vertical link with no problems. I fabricated
brake line fittings and brake hose.
