Dually question

[B_derK20]

Hi all, I just stumbled onto this place Friday night. Guess who didn't get much done over the weekend? I have an '83 K20 with a couple of heavy duty parts I'd like to add and a couple of questions.

1. I currently have a DRW dana 60 front I'd like to swap in. I have access to a DRW dana 70 from a cab & chassis combination that I can get for next to nothing. Which would be cheaper and or easier, turning my SRW into a dually or buying SRW hubs for my dana 60 and converting it over. It would have to be regeared to match the 14 bolt FF that I was planning on swapping in. The dana 70 and 60 are geared the same.

2. Can you even buy dually fender flares as reproductions or do they have to be sourced from a donor truck?

3. Are the dually dana 70s different widths depending on if the truck was a cab and chassis or a pickup bed?

Thanks in advance. This place is great!
