I did some looking around in those forums and found some goon info.
Found this place Improved Racing GM LS-Series Engine Oil Pan Dimensions
. with part numbers and info and pictures with dimensions!
Looks like there GM Truck / SUV Oil Pan may work?
Also sent some Emails for more info and compatibility with my engine.
Compatibility is the big thing, I hate waiting just to have to send something back and start all over.
From what I have been able to find out one style Pan could fit many makes and models.
But wont take the chance without some verification, that's why I was looking for some one that has first hand knowledge.
