Some pics that I took a while back, but only uploaded the other day, which I hope may be of use to anyone who is repairing / reconstructing the front chassis rails.
A right hand front chassis rail is shown (this is an NOS Volvo panel):
Captive nuts for bumper irons & ARB mounts
Mounts for steering box (or idler if the other side or lhd)
Similar internal reinforcement at the back of the rail (above the rear mount for the crossmember)
Rear mountings for crossmember
Front mountings for crossmember
In situ with inner wing
