I have an easy way to set the lenght of the tie rod bars so you can at least drive the car to get it alinged without wearing your tires out.

Get a piece of wood and pound a nail into it. Lay your old tie rod assemby on top of the wood and press it up against the nail. Get another nail and mark where the other end of the tie rod sits on the wood. Slide the tie rod away and pound that nail in but not too far. Put the tie rod back in place and bend the nail in or out until the whole asembly will just slide through.
Adjust your new assembly so that it will just slide though like the old one. Make sure you keep track of which side you are working on because they won't be the same in most cases.

This will be very close to the original dimension. On old beaters sometimes I never did anything more than the nail trick. Saves me 50 bucks or more and an hour or two waiting for the job to be done.
