After reading about how the B&M Ripper shifter has an unusally large thread, I've learned that only stock shift ***** from both third and fourth gen cars are the only ones that will fit (other than those from B&M themselves). We have a Ripper in my brother's 98 Z28, and it currently has the stock shift **** on it, which fit without any problem. Doesn't that mean that any aftermarket shift ***** for 4th gens will also fit the third gen Ripper?
