I contacted Addco asking about Bars for 55-56 Ford. They don't supply them new any more for this Application.

  

As miker points out, adding a rear anti roll bar can make the car feel more stable, but if the bar is too big compared to a front one, it can lead to rear oversteer problems. Which is likely why most cars don't have a rear one or if they do, it's usually considerably smaller than the front one..

thanks miker, i'll check

I've done a number of rear bars, various cars. Back in the late 60's I put an Addco on the back of a 55 bird. I've had one on my current 55 before I redid the rear suspension. Happy with both. But it does have to be matched to the front bar. I mismatched the bars on a car once. Felt really good in the dry, first day it rained I spun the car in an intersection. If Addco has a pair of bars, they're probably made to go together. They're still around.

Did it on my 56..  drill holes .. bolts 'n' banging.. had to gently bend brake lines etc even made some spacers to try level the bar.. can be done . yes its worth it. BUT it was to match another aftermarket one on the front.
