1965 Barracuda Question

Hey everyone,

I found a 65 Barracuda that is just a parts car if that. I have a few questions. I'm thinking of building a T bucket with a 50s-60s era look.

Can you tell me what rear end a slant six car would have?

Also what is the length of the rear? I think I need from back plate to back plate messurment.

Also what trans would the slant six have?

I don't know if I could use the steering box in the T' bucket or not. I know they (Hot Rod boards) say to use the Corvair and Vega boxes but reverse them. I don't know if the steering box in a Barracuda would work.

What is the steel wheel size?

I want to go steel wheels both skinny up front and back with white walls.

Thanks for any and all info you can give me.

As you can see the car is gone.
