The portion of the Putco Push-Up Tie-Downs # P99901 that goes into the pocket on your 1950 Chevrolet 3100 will be 1-3/8 of an inch by 1-3/8 of an inch and it is 3-1/2 inches long. That is with no rubber block installed. With the thickest block installed it will measure 2-5/8 inches wide and with the rubber grommet installed the length will be 3-5/8 inches long.
So as long as the measurement of the stake pocket is within those bounds you will be good! view full answer...
