Hey guys, just wanted to know if the hawks complete ls1 conversion mount that can use the stock arms changes anything with the oil pan configuration?
I'm in Australia so 4thgen sumps are hard to come by and $295US from hawks seems a bit rich for a stock sump.

As for the oil pan situation, unfortunately, the monaro uses a front sump system, which falls exactly into the thirdgen k-frame and steering.
Unfortunately, unless you go to an aftermarket pan, the f-body is the only sump that will work.
Hawks is designed around a Pull out f-body LS1. So their kit only works with the f-body pan.

damn it.
How much can you get a f-body ls1 sump at the wreckers over there?
Coz the one hawks has just seems a bit too over the top
