For those with Syncros.
First step in dropping the waterboxe is to remove the special Syncro
skid rails. I ended up removing them all, front to back, but
realized this is not necessary. The rear rails have two bolts at the
mounting point just in front of the tranny. One of these bolts
supports the front rail but you can remove it and then re-install it,
thereby leaving the front rails in place.
