Is a truck rear sump pan interchangeable with a T Bird pan ?

I am under the impression that there are two different truck rear sump pans.

If so what are the differences between truck pans and T Bird pans.Seems I"ve heard the baffle is different in the truck pan and also the drain plug is a different size.Possibly volume of oil?

Who can tell me whats what?

Thanks,Oldmics

Here are pics of the three basic rear sump Y-Block oil pans.  As 314 mentions, the HD truck pan holds an additional quart of oil.

  

 

 

The top pan is the HD pan, the middle pan is the truck pickup pan, and the bottom pan is the Thunderbird pan.

Are you able to measure the lowest point of the middle section on the Truck pan ? I need it to be less than 6" deep so my Tie will not hit it. This will tell me weather I purchase one or not.

Thanks,
