My friend in South Africa is having trouble removing his shifter linkage to convert to a short shifter. He has removed the 4 top bolts and the 17mm bolt on the side. Car is in neutral but it won't release. I had mine done by a mechanic so haven't done it myself, but remember reading on here that a common mistake is made by not unbolting an obscured bolt. Can someone refresh my memory so I can relay this to our chum in South Africa please.
