No factory rear alignment gear?

[bad]

I needed an alignment because I slid into a curb with my front driver's side wheel one icy morning. Midas said somewhere in the $60s for a two wheel and somewhere in the $90s for a four wheel alignment. Another place near my house said $79.99 for the four wheel alignment and they had no separate prices for two or four wheel. So I went with them. First mistake was not asking about taxes and fees, because it came to $90 anyway, where as I know midas always has their fees included in there stated prices.

I got the print out with the before and after settings of my car. The front had been changed and aligned. The rear wasn't changed at all. The cambers in the back are fine, but the toes aren't.

Left Rear toe: 0.48 degrees.
Right Rear toe: -0.25 degrees.
The Rear total toe seems fine though: 0.23 degrees.

I asked the guy at the garage to give me the whole alignment that I paid for but he said there is no factory rear alignment gear on my vehicle and that I would have to pay extra shop labor for them installing shims to fix that and that it isn't worth it unless I notice excess tire wear.

So lesson learned; for anyone who has an alignment problem and you are at least 90% sure that it is your front only, go somewhere that lets you pay less to only get the 2 wheel alignment.

Besides that, I was just wondering what you all think or if you know that he is telling the truth.

Thanks.
