LM7 5.3L to F-body oil pan

[mrhurt73]

I have a 2001 LM7 5.3L engine i am putting in a 1979 chassis that is lowered on airbags. when the truck is lowered, the oil pan sits right on the ground.
kind of thought it would.

i was thinking of using a F-body oil pan to gain plenty of clearance.

i found these numbers, anybody know if they are correct? or anybody made this change?

12558762 oil pan
12558251 pickup tube
12558253 windage tray

any advice would would be great.
