I mean, I haven't seen it. But the suspension design is pretty dang close. Heck I even looked at some of those forward look LCA's, they look very much like the '73/74 B body LCA's that allow for more suspension travel than the A-body stuff.
I have no doubt a road race Christine would work. How cool would that be?
...and I wanna say also, I think the HDK kits are probably by far the best at what they offer. I think deciding what factory and aftermarket suspensions can do better than the other is splitting hairs, mainly because the factory design is so dang GOOD, it can pretty much do everything. If you want header clearance, coil overs and a rack and pinion, I think the HDK systems are head and shoulders above the rest. Also, no one can argue the HDK stuff isn't more modern. I don't have enough sense and certainly zero experience with aftermarket suspensions to say what WORKS better. I've done a good bit with the factory design and I can testify to how well it works.
