Dans auto is correct. The Vipers are easy, if you can say that, to restore to factory specs from frame damage, at least as it pertains to a front stub or a rear stub.
Two guys here in town have wiped out the front end of their Vipers frame and all. Just cut the front stub off and weld a new stub in place, a surface plate helps but in no way is it required. The Viper has some very easy points to remove the front stub from. Vipers are very much like our racecars in that aspect. I've heard of guys having their Viper frame "bent" back into place on a frame machine, that is a very incorrect way to repair frame damage on a Viper.
I would much rather have a full frame car than a unibody car. Especially if you are fixing frame damage.
