Ive watched guys swap from coil to leaf,i dont know why,but what was needed was the coil crossmamber,the trailing arms,panhard bar,shock brackets etc.it isnt a big deal,but i like my leaf rear trucks for some reason,over coils.guess thats why everything gets a 67 GMC frame,well that and 67 GMC earlier ones have no VIN numbers.if you need a coil frame $250 in AZ,ill give the trailing arms for $25 nice rust free,can sell a rolling chassi if needed.
