I don't know how to find out what will fit into the rear axle ( i only want one in the back) and like how many splines i need and what would fit and so fourth, i want a selectable locker not automatic, and also i don't know what is a good locker like eaton erb or OX lockers, what would be the best, and would work for my truck?

I have a 2013 Chevrolet Cruze LS 6 speed manual transmission. I do not have cruise control on my Cruze. Can I install cruise control?

Use a proper cage if driving, depending on his size. If he's trained to sit in a seat, back or passenger seat beside you, he must be buckled. If flying, check with the airline as to what they allow, ie. approved cage with a locked door and water w/ food. It's happened were an airline baggage handler has opened a cage to let out a dog but he bolted and was forever lost. If your dog is a registered purebred and sending him to a show, you should have him insured.

French manufacturer Peugeot is showcasing its hybrid air technology - a system which allows a car to be driven around town powered by little more than compressed air.

The idea is to produce a hybrid which has low emissions and doesn't need a battery - because batteries are heavy and expensive.

At the Paris Motor Show, Theo Leggett took a look around the 208 Hybrid Air - a concept car that brings a new meaning to the term "gas guzzler".
