Hi,

Here's another thread about this windage tray.

Jegs Windage Tray

I just finished putting one on my 400 with a factory 402 pan. The pan rail was pretty straight but with the thickness of this composite tray, I'm sure some minor dimpling would still be resolved.

I have about an hour's worth of run time with the car on jack stands and probably another hour this weekend while I finish some other work. So far, no leaks and I've checked the pan rail area pretty closely. I'm very satisfied with this, especially considering the price.

If someone wants, I can post a picture of the pan rail area to show the thickness of this part once it's installed.

Mike.
