84 B2000 project

Here's a few pics of my pre let me know what you think. I traded for this a few weeks back so all of the hacked up stuff was done by the previous owner.

looks like a descent start man. what is that hood and headlights off of? i like it man.

The previous owner said it was off of 74 B2000 but I think it's off of a 79-81 model. The rear frame is hacked up pretty bad but I plan on doing a narrowed back half and rearend to make room for the rims.

Should I build a 3/4 frame and stock floor it or should I leave it be?
