I saw a write up on one of the GP boards a while back about using rear door handles on the front, as they were keyless. Some modification had to be done, as the arm that pulls the rod for the latch mechanism needed to be moved from the from the front to the back. I think I may have found an easier solution.
I was at the junk yard a while back, and I needed a rear driver's side door handle for my 02 Impala. I found a 4dr GP in the yard with the same paint code as my 02, and the door handles looked to be the same shape and size. I noticed that a lot of GM cars from the era used door handles that looked exactly the same, but for some reason on the back of the GP handle it said "Pont Only". So I bought the handle, hoping to replace the broken one on my Impala. I got the broken one out, and on the back, the arm was on the wrong side. I was unable to use the GP handle on my Impala, but I immediately thought of the GP guys trying to put rear door handles on the front of their cars for the keyless look. If you guys use Impala, Regal, Century, etc rear door handles, they will work in the front without modification.
Here's a comparison of the two handles:
Rear driver's side door, Impala on left, GP on right.
Impala on bottom, GP on top.
Note that the handles are identical aside from the placement of the arm.
