Where can I find a front bumpstop for my 09' that is 1/2" longer than my OEM bump....

I am running top plate spacers with my coilovers and want to make sure I do not over compress my coilovers. I want to accomplish this by adding a larger bump stop, but I do not know where to get some.
Can someone please let me know what size I need and where I can find it?
Thanks in advance.

 

Okay heres the solution. Energy suspension 99135 http://www.energysuspensionparts.com/proddetail.asp?prod=9.9135

You bolt it on so you just have to obtain a similar threaded bolt and voila! You can trim it too depending on how much you have lifted it. I would measure what the distance is before lifting and then trim the bump stop to fit to mimic the same distance between it and the lower control arm. here are some pics for your viewing pleasure
