Different

The ali pans also use a different suction tube to the steel pans.

Seems to me the best thing to do would be to plug the hole in the pan and just use the existing dipstick location in the block. Anyway here is the pic of the dipstick location.

The dipstick through the block has a tube on the inside of the block, below the pan rail to guide that type of dipstick past the spinning crankshaft - and it interferes with the ali sump So it has to be removed to fit that nice shinny ali sump you have - which someone has removed the outside dipstick tube from ..... So you need to find the tube AND correct dip stick before you can use that nice polished alloy sump. I have a similar problem - need the dip stick too! As Bob says - they are hard to find

Ali pan & tube

Here is a pic of an oil intake pipe and an ali pan with its dipstick tube.
There is no guide down inside the pan as the dipstick emerges quite low down near the floor of the pan. I guess a dip stick can be made up out od any old Chevy flexible stick - cut to length and with the oil levels remarked onto it ......... Oh! It has a dipstick in it too - passed this set up on eBay when it went up over $100.... cheap now???
