Bringing “Old Butternut” Back to Life | 1981 Peterbilt 359 Big Bunk Upgrades!

Описание: 👉www.SemiCasualShow.com👈    / @semicasualshow  
Old iron never dies… it just gets upgraded.

In this episode, we spend the weekend wrenching on “Old Butternut,” our 1981 Peterbilt 359 big bunk with a stretched frame. This classic square-nose semi truck has the look, the stance, and the history — now we’re dialing in the details to bring it back one step at a time.

In this video we:
👉 Fix a broken tach cable
👉 Track down and repair wiring issues under the dash
👉 Install brand new chrome pedals
👉 Battle a stainless steel door hinge (we got 359 door lined up right)
👉 Install custom hand-built chrome vent covers from 12ga Customs
👉 Give this old Peterbilt a much-needed wash

There’s something special about working on a 1981 Peterbilt 359. The mechanical simplicity, the classic long hood styling, the big bunk sleeper, and that stretched frame stance just hit different compared to modern trucks. These are the trucks that built the industry.

If you’re into:
✔️ Custom semi trucks
✔️ Classic Peterbilt 359 builds
✔️ Old school big bunk rigs
✔️ Stretched frame show trucks
✔️ Transportation industry content
✔️ Shop upgrades & wrenching videos
…you’re in the right place.

We’re not restoring this truck overnight — we’re bringing it back piece by piece whenever we get a free weekend in the shop. More upgrades are coming soon.
