Transmission Cooler and Brake Lines

Does anyone know what diameter the transmission cooler lines and brake lines had when they were stock on a 71?

Trans: TH 350
Brakes: Factory Disc up front

The trans cooler lines look much larger (diameter-wise) than the brake lines. I just need to know the original, stock size of each.

Thanks!

Trans = 5/16
Brakes = 3/16 and 1/4

Thanks a lot!

From the junction block to the passenger's side caliper, it is the smaller one (1/4") right?

I, of course, meant 3/16 being the smaller one.

Yes, 1/4 inch from proportioning valve to that junction block that splits it from left to right and 3/16 from there out to each wheel.
