'69 fastback frame rail/torque box question--with pics
I have a '69 fastback that has been wrecked and shoddily repaired in the past...and to add insult to injury, the LF frame rail under the tower and both shock towers are rusty. On top of all that both front aprons and core supprt have been cut off and the strut rod housings are mangled/bent.
Needless to say, I need pretty much everything from the firewall forward. The only salvageable part is the RF framerail...and it may be tweaked since the framerail distance varies +/- 8mm between the end of the rail and the shock tower.
Here is where my question comes in:
I just bought a complete Mustang front clip with big block shock towers. I am trying to decide the best way to swap it in and keep everything lined up within specifications.
My thought is to separate the frame rails/shock towers/aprons as an assy from the firewall and torque boxes on both the clip and the car while leaving the seat support rails in place as a guide as to where everything should line-up when going back together. I figure if I start with the whole car level and the front frame rails level--that I should be able to slide the new rails/clip into the floor pan supports/rails until:
the aprons mesh the firewall perfectly
the frame rails slide to the proper depth in the floor supports
and the front frame rails are level like the originals were
Does this sound like it would work?
How hard is it to separate the frame rails from the torque boxes without hurting the rails or torques boxes? (both the car and clip have VERY solid torque boxes) Should I leave the torqueboxes attached to the replacement frame rails and swap them in also?
