I've got a 1971 FJ55 on the way. I'm going to upgrade to rear disc brakes right off the bat and will more than likely be replacing the master. Probably will do lines throughout also.

What I don't recall is whether the 1971 had the standard toyota metric brake lines or the small sized.

Anyone?

9mm for 07/70 and earlier trucks, 10mm for 71 and later trucks.
