I installed a 454 with turbo 400 in a 1965 Impala. It had a 283 with power glide, on the column. Here's the problem when in reverse which is on drive reverse light are on. how can I correct this.

GM spread out the detent spacing between park, reverse, and neutral> for safety reasons in the mid 70's .
Ford was a little slower fixing the problem. You could start lifting the column shifter and when you went thru reverse the Hyd valve in the trans would be in neutral before the column locked in the park detent and/or the trans park pawl engaged to lock the car from moving. . if you got out of the car to close the garage door and did not have the column locked in park , bumped the steering wheel, or leaned on the door the shifter could slip back into reverse . people got killed from that design tolerence problem. Thats why the decal or owner's manual always said set the park brake, shift into park and turn off the engine before exiting the vehicle. The detent spacing on the column must match the detent spacing in the trans.
