Hi, I was in Colorado last week and got stuck in the snow/iced roads. Luckily, I had purchased tire chains so I was able to get out after nearly freezing my fingers off. So, I have a question regarding locking differentials. I've been reading that it was an option on the 99 express, but mine clearly does not have it. Has one of you retrofitted your van with a locking differential? What aftermarket options are there? I did some web searching but did not find stuff for the van. Any ideas/suggestions? Thanks!

Thanks! Looking into this now. It looks like there are 2 or 3 options depending on whether it has a c-clip or not. Best regards, joe99van
