This unused BFGoodrich Space Saver spare tire from a 1971 Pontiac Firebird had been folded up for more than 50 years.

Designed to save trunk space, these inflatable spare tires were considered advanced technology when they were introduced.

Would you trust it on a long road trip?

This is what happens when the shop is PACKED with projects. 👀

End of the day and the overflow lot is full. Moving cars around, making space, and getting everything back inside before we close up.

Tonight's lineup:
• 1934 Ford
• 1970 Chevelle SS
• 1969 Camaro
• 1966 Impala 427
• 1967 El Camino
• LT1-swapped 1970 Chevelle

And yes... we know the Chevelle is dusty. 😂 That's what happens when these cars actually get driven and worked on all day.

Which one are you firing up first? 🔥

A quick throttle hit from this 2016 Shelby GT350.

Ford got a lot of things right with this car, but the sound might be the best part.

GT350 or GT500?

This shop is full of hidden survivor cars and original factory details.

Original vinyl tops.
Documented Super Sports.
Garage kept classics.
Even a wild old school Hot Wheels style ’34 Ford hiding in the back.

Sometimes the coolest cars aren't the fully restored ones. They're the ones that somehow survived all these years untouched.

Makes you wonder... what's hiding in your garage right now?

There’s a reason original GM interior parts from the 60s and 70s still feel different than many reproduction parts today.

Factory GM armrests used metal reinforcement underneath the padding and vinyl, while many reproduction versions switched to plastic.

Even some reproduction door panel headers went from metal to plastic.

Little details like this are the kind of things survivor car enthusiasts notice immediately. The factory craftsmanship back then was just different.

What reproduction part do you think still misses the mark the most?

Most people would rip this carpet out... But on survivor cars like this, where a little patina is okay, we’d rather re-dye than replace.

This old carpet was badly faded, so instead of installing new carpet, we brought the original color back using RIT dye and a simple pump sprayer.

The transformation happens FAST. 🔥

Would you save the original carpet or replace it completely?

The 5.2L Voodoo in the GT350 is still one of the best sounding modern V8s Ford ever made. 🔥

Happy Memorial Day 🇺🇸

As we enjoy time with family, friends, and a little BBQ today, it’s important to remember the reason for this holiday and the heroes who made those freedoms possible.

My grandfather served in the U.S. Air Force during WWII with the 388th Bomb Group and earned a Purple Heart.

My father proudly served in the U.S. Navy during the Vietnam War.

Today we honor and remember all those who served and sacrificed for our country. 🇺🇸✝️

Thank you to all who served!

There’s a reason original GM interiors from the 60s and 70s still look different than reproduction parts today.

These factory door panels used layered construction underneath the vinyl to create that deep ribbed texture you just don’t see reproduced correctly anymore.

I forgot to mention in the video that the window crank k**b originally started out clear from the factory. Over time, they usually turn into that yellowish tint you see on original survivor cars.

It’s little details like this that separate original survivor cars from restored cars. The factory craftsmanship was just different back then.

Did you already know GM built their door panels this way?

This Mustang GT convertible sat for years after being inherited from the owner’s father.

Now it’s getting a full mechanical and suspension restoration:

302 with a roller cam
C4 transmission rebuild
Engine bay detail
Suspension and brake restoration

Some people would opt to keep the original 289 engine. We're going for a bit more power with a 302.

What would YOU do?
