Project and questions

[RACERSD2]

After attending the Hot Rod Power Tour stop here in Chattanooga the wife and I have decided to try and make it next year. I went searching for a older burb and I found a solid 71 faded black chevy burb with no engine or tranny already lowered with truck rallys, a cowl hood, a 80s style conversion van wing on the back. The interior has later model buckets with a grant wheel. No back seat.

It was a old TN TDOT truck so its original color is uuuuuugggglllyyyy orange.

Upon picking her up i noticed that the "bed" part of the floor was made out of 1" plywood at first i was ill but then noticed there was every single "factory" mount underneath it, the floor was cut perfectly to match the body and frame and the holes lined up when i looked under the rubber mat the floor was painted orange just like the interior and from the looks of it it was painted at the same time as well The plywood is not bent warped or chipping away.

Right now the project will be a rat rod looking truck with a 5.3/4L60. Satin black to match our miata race car. Switching out the grille to a GMC (I like the quad headlights) with a updated interior

The goal is to run the HRT, tow our race car and sell, promote our t-shirt line loosenutz at loosenutzgarage.com

NOW question time....
Is it common for burbs to have wood floors?

I have front discs and drum rear what size/kind of rear end do they have (10/12 bolt)?

Adding power steering the burb doesnt have it so will this mean a whole steering box change? If so has anybody tried the electrical power assist?

Has anyone done a suicide door to their "3rd door"?

The tail lights are different than the trucks are there LED or replacements available?

Thanks in advance.
