I believe at least for 28 Chevy cars that was the first year for front brakes. If trucks followed the same rule than that is an easy to tell.

I have a 28 car, but I forget where the tag is, probably on the firewall, engine side.

Also, the 28 had plenty of room under the hood and a deep fan shroud, this in anticipation of the new 6 cylinder in 29. I don't think 27's have that much extra length under the hood?
