Doug Jennings told me that the "sagging" problem with front suspension crossmembers was only an issue with Tigers (and Algers). According to Doug, the combination of the notches to accommodate the steering rack (loss of beam strength) and the increased engine weight of the Tigers resulted in the center of the crossmember slowly bending to the point that camber could not be properly adjusted. His approach to preventing the problem was to add reinforcement plates in key locations and to fully weld the seams in the crossmember (rather than stitch welds). He did not reveal how he repaired a crossmember that had already sagged.
I am pretty sure that Joels comment "Start with the fwd. Spring mounts" referred to the front mounts for the rear suspension leaf springs which take all of the forward thrust loads during acceleration, at least half of the lateral loads during cornering and carry about half of the rear vertical loads. IMO, they are marginal for a "stock" Alpine, much less for a V8 Alpine.
