I always wondered why the rear intermediate crossmember was at an angle instead of straight across, I'm guessing that's part of this deal here with the shock mounts, it's all some sort of compensation for the track bar in direct relation with the trailing arm suspension, but I never gave it much thought, I just shrugged and thought they must have a reason and I don't really need to know why as long as it works
Ya know Vic since you have all the time in the world you could fabricate a 4-link just for fun, it wouldn't cost a lot and would be really cool.
