This top restraint must be used with a Taylor restraint and please specify brand of injector when ordering. Easy to install on the Enderle hat simply take the bolt out in the center of the injector faceplate and install the hangman strap assm. on the Veney the racer will have to drill and tap a hole to make the restraint work.
