hey make sure u have the set screws tight in ur cvs - if u have the setscrew type...
doing a fast pass with my rally, it suddenly locked up and spun past me - the right rear cv pin had worked loose and cut threw the hub from pillow ball to pillow ball. no other drivetrain damage which kinda surprised me. and yes that is surface rust...
still a single speed rally setup, to hell with 2nd gear, i have a 18t 1st gear pinion - works great!
whoops - forgot, pic of typical break in my cv... always the same.
so no, still no engine mounts.
