Hello Dennis ,Thanks! - The test drive was really good plenty of speedgazm!!=D

The clk's alternator and a/c pump bearings were much much smoother, also the power steering pump had less play so I used all three!(all have same part numbers as C43)

The final recipe was all CLK55 parts - The engine,trans,prop shaft,entire rear axle drive/subframe,centre muffler and rear muffler everything just bolts in but of course you need diff recess for clearance!.
There are many many other clk parts i used, I will write a list at some stage!.

I will snap some interior shots once the parts arrive and I have repaired the cluster ribbon!

Cheers!
