1970 CUDA Restauration

[1970CUDAAAR]

Hi!
Still working on my restauration. Im planning to buy the rear window loover - comments where is the best place to buy. Also I need to replace the rear-end gear. I presently have a 3:23 ratio with a 440 - should I move to a 3:55 ratio?

Year One has aluminum and plastic. They have a really good reputation:

I was selling a Lot of the best alum louver repros out there 16 years ago , but they are not making them any more , not sure what is out there now .

I really like those rear window louvers on the 70 Cuda as well. But I don't want to mess up my numbers 383 four-speed car and devalue it.
