What was the weight of the 54 Buick?
4400 and change..... I did do some extra gusseting on the crossmember and the coilover mounts, I always do regardless of weight... The rear steer could be a problem... Not a lot of rear steer units out there. What width are you going to need on the crossmember???
I have some sources for crossmembers, and also I do business with a smaller company that could possibly be talked into making the A-Arms out of chrome moly.... At least I was able to talk them into it a couple years ago for a "special project" that was going to be subject to some heavy cornering loads on a road course... Could do some checking for you if you want?????
