After blowing up my selecros I also just use the stock drive flanges. For driveing down the road I have a set of aluminum bicknel flanges of a dirt track car with the splines boared out to keep the dirt out. When I get where im going I just take out the bolts and swap them out. If you change the hub out to the 91-93 dodge style they are the same as a chevy and there are alot more options of locking hubs.
