beautiful truck got plans? bernie- quick n easy way to tell the 18r trucks from the 20r trucks... your grill equals 18r, newer "open mouth" grill equals 20r. 20r's started in '75. i was able to bolt my 18r alt (with 18r upper bracket) to a 20r. let me see if i can find a pic... score one for the home team, 18r alt n upper bracket on a 20r. i would assume a 20r upper bracket with a 20r alt would fit on a 18r.
