I've been looking now for about a half hour and have not found anything conclusive on the LT1 - LS1 upgrade. Is there a good install site, does anybody know if its possible to do the swap with out swapping the spindles? My cars in the sig and I ordered some new calipers and rotors for the front off a 98 Z. If there is a way to alter my existing spindles with out making them dangerous or unsafe please let me know. Thanks in advance for any information.

 

try here http://www.fbody.com/tech/details.cgi?id=30, even tells you the tools and parts required. i don't think that you can do the swap without swaping the uprights because of the difference in size of the brake disks
