altercation vs hemi denny

I am ready to pull the trigger on a front end for my 68 cuda. trying to decide which would be best for me. I am looking for a power steering set up. street car.

questions:

which is lighter
how long will it take to get
which gives the most room

I thought I saw that the hemi denny has the stock width and the altercation is much wider. can the altercation be made with stock width? I plan on using `15" wheels. is one set up better for this? any advice would be appreciated...
