My 15 year old son bought a 73 w100 for his first vehicle. We are in the process of getting it all fixed up for him. We are putting a new steering wheel on and noticed that the stock automatic shifter is really sloppy and you don't even have to pull it toward you to select the gears. It seems like the spring that pushes the shifter forward is either too small or has just been smashed from years of use/abuse. Is this a common issue? Can i either stretch the spring out some or put something behind it to push the spring out more? Thanks in advance for any help or advice.
