Hello all! This is our first tech question as we are new here. The wife's 66 Cutlass has 2 different window cranks in the back seat. One is almost straight (1/4 in. curve) , the other is much more curved (about 3/4 in.) The problem is the straight one rubs the panel at the 12 o'clock position when cranking. Any thoughts as to what is correct handle, or what year or model has the bigger curve?
