i have an 82 monte that had a th 350 in it with a stock floor shifter but i am missing the linkage since the car didnt come with the motor and trans. i swapped in a 200 4r out of a 87 monte with a column shifter. will i need to find a new aftermarket shifter or one out of a car that originally had a 200 4r floor shift? or can i modify the one i have to make it work? also where would i be able to get the right linkage to convert my 200 4r to a floor shift since it came out of a car with a column shift?
