front apron, core support jig

[72restocuda]

looking to replace my essentially my 71' cuda entire front end, rails, shock towers, aprons, going to a 26" radiator opening. I've seen on other e-body sites people that have made jigs that mount in the shock tower holes and line everything up. My car has front end damage and the driver side rail is up maybe an inch.  I built a frame jig to sit the car on and will be doing that hopefully tomorrow but if anyone has a front apron jig or something like that they made and no longer need that would be great. Thanks
