I have used and sold many of their pans. Are you getting pt# 31557 10 qt jet pan? Remember it does not come with a pick up!! The dip stick is a screw in type with a rod welded onto it. You will need to mark it where you want your oil level. With 8 1/2 to 9 qts in the pan you will be fine. If you put a quick drain oil line on it, you will need to drill and tap the oil drain plug for it to work.
Also make sure to check the clearance from the p/u to the bottom of the pan. 1/4 to 3/8 inch is acceptable.
If you have a problem getting this pan let me know and I will see what I can do for you.
